 Unveiling the dynamic extensions of neurons

Published

on

 Neurites, the intricate extensions of neurons, play a vital role in the development, function, and maintenance of the nervous system.  

These complex structures, comprising dendrites and axons, enable neurons to communicate with each other and with other cells, facili­tating the transmission and processing of information.

In this article, we will delve into the fascinating world of neurites, exploring their structure, function, and regulation, as well as their implications in neurological and psychiatric disorders.

The structure of neurites

Neurites are composed of various structural compo­nents, including the cytoskel­eton, neurofilaments, and synapses. The cytoskeleton, comprising microtubules, microfilaments, and inter­mediate filaments, provides mechanical support and shape to neurites.

Neurofilaments, specialised proteins, offer additional structural support and stabili­ty to neurites.

Synapses, the specialised structures that enable neu­rons to communicate with each other, are composed of a presynaptic terminal, a syn­aptic cleft, and a postsynaptic density.

The function of neurites

Neurites play a crucial role in the transmission and pro­cessing of information within the nervous system.

Dendrites, the branching extensions of neurons, receive signals from other neurons, while axons, the long, thin extensions of neurons, carry signals away from the cell body.

The dynamic interaction between dendrites and axons enables neurons to communi­cate with each other, facil­itating the transmission and processing of information.

Regulation of neurites

Neurites undergo dynamic changes throughout develop­ment and maintenance. Key processes include neurite out­growth, neurite pruning, and neurite regeneration. Neurite outgrowth involves the growth and extension of neurites during development, guided by various molecular cues.

Neurite pruning, a process where excess or dysfunctional neurites are eliminated, re­fines neural connections and maintains neural homeostasis.

Neurite regeneration, the process of regrowing damaged or severed neurites, is crucial for recovery and repair after injury or disease.

Dysregulation of neurites in disease

Dysregulation of neurites has been implicated in various neurological and psychiatric disorders, including Alzhei­mer’s disease, Parkinson’s disease, and schizophrenia.

Abnormal neurite growth and pruning contribute to the development of Alzheimer’s disease, while dysregulation of neurite growth and main­tenance contributes to the development of Parkinson’s disease.

Abnormal neurite develop­ment and maintenance have also been implicated in the pathophysiology of schizo­phrenia.

Conclusion

Neurites, the dynamic extensions of neurons, play a vital role in the development, function, and maintenance of the nervous system.

Understanding the struc­ture, function, and regulation of neurites is essential for elucidating the mechanisms underlying neurological and psychiatric disorders.

Further research into the biology of neurites will pro­vide valuable insights into the development of novel thera­peutic strategies for treating neurological and psychiatric disorders.

As we continue to unravel the complexities of neurites, we move closer to unlocking the secrets of the nervous sys­tem and developing innova­tive solutions for neurological and psychiatric disorders.

Seeing the child, not the label: Supporting children, teens with ADHD

Published

on

Attention-Deficit or Hyperactivity Disorder (ADHD) is often mistaken for laziness or indiscipline. In consulting rooms across Accra and in reports from school teachers, the pattern repeats: children who are bright but forgetful, parents who feel helpless, teachers who see incompleteness.

 Research is clear-Barkley (2015) and others describe ADHD as a difference in the brain’s regulation of alertness, impulse and working memory, not a lack of effort. 

The family’s role begins with structure. Regular sleep, predictable meal and homework times, and a simple visual list (uniform → books → water → corridor) provide the external scaffolding of these children need. Praise what is completed—“You opened the book and wrote the first sentence”-instead of rebuking what is missing. 

Schools can help by seating the child front-row and centre, giving short written plus verbal instructions, allowing brief movement breaks, using quiet nonverbal cues and, where possible, grading effort and method as well as neatness. These adjustments reduce conflict and raise submission rates without lowering standards.

Couples and caregivers should share roles: one grounds, one pivots, and both protect rest. Shame-“bad parenting, bad child”-needs replacing with fact: different wiring, needs scaffolding. 

Outcomes improve not by promises of perfection but by daily routines, clear limits and warmed connection. One homework slot kept, one instruction chunked, one calm repair after blurting-these small wins shift the family climate and let the child be seen beyond the label.

Smooth transfer — Part 2

Published

on

After two weeks of hectic activity up north, I drove to the Tamale airport, parked the car at the Civil Aviation car park as usual, paid the usual parking fee and boarded the plane for Accra.

Over the last two weeks, I had shuffled between three sites where work was close to completion.

One was a seed warehouse, where farmers would come and pick up good quality maize, sorghum and other planting material.

The other was a health facility for new mothers, where they were given basic training on good nutrition and small scale business.

And the third was a set of big boreholes for three farming communities.

The projects usually ran on schedule, but a good deal of time was spent building rapport with the local people, to ensure that they would be well patronised and maintained.

It was great to be working in a situation where one’s work was well appreciated. But it certainly involved a lot of work, and proactivity. And I made sure that I recorded updates online before going to bed in the evening.

When the plane took off, my mind shifted to issues in Accra, the big city. The young guys at my office had done some good work. They had secured five or six houses on a row in a good part of the city, and were close to securing the last.

When we got this property, unusually, Abena greeted them casually, and appeared to be comfortable in the guy’s company.

I was quite disappointed to hear that, because until the last few weeks, it seemed as if Abena and I were heading in a good direction. Apart from the affection I had for her, I liked her family. I decided to take it easy, and allow things to fall in whatever direction.

Normally I would take a taxi to her house from the airport, and pick her up to my place. This time I went to my sisters’ joint, where they sat by me while I enjoyed a drink and a good meal.

“So Little Brother,” Sister Beesiwa said, “what is it we are hearing about our wife-to-be?”

“When did you conclude that she was your wife-to-be? And what have you heard? I’ve only heard a couple of whispers. Ebo and Nana Kwame called to say that they have seen her in the company of—”

“Well said Little Brother,” Sister Baaba said. “By the way, Nana Kwame called an hour ago to ask if you had arrived because he could not reach you. Someone had told him that Jennifer had boasted to someone that she had connected Abena to a wealthy guy who would take care of her.”

I was beginning to understand. For some time, Abena had been asking me what work I was doing up north, and after I had explained it to her, she kept asking. So I think Jennifer fed her with false stories about me in order to get her to move to the Ampadu guy. Jennifer must have been well compensated for her efforts.

“In that case,” Sister Beesiwa said, “you should be glad that Abena is out of your way. She is easily swayed. Anyone who would make a relationship decision based on a friend’s instigation lacks good sense. I hope the guy is as wealthy as they say?”

“Who gets wealthy running a supermarket chain in Ghana?” Sister Baaba said. “Our supermarkets sell mostly imported products. Look at the foreign exchange rate. And remember that Ghanaians buy second-hand shoes and clothes. Supermarkets are not good business here. Perhaps they are showing off that they are wealthy, but in reality they are not doing so well.”

“Amen to that,” I said. “I’m beginning to understand. For some time, Abena had been asking me what work I was doing up north, and after I had explained it to her, she kept asking. So I think Jennifer fed her with false stories about me in order to get her to move to the Ampadu guy. Jennifer must have been well compensated for her efforts.”

She said that David Forson was only an agricultural extension worker in the north who did not have the resources to take care of a beautiful girl like her. And apart from being wealthy, the guy comes from an influential family, so Abena had done much better leaving a miserable civil servant like you for him.

“Amen to that,” I said. “I’m beginning to understand. For some time, Abena had been asking me what work I was doing up north, and after I had explained it to her, she kept asking. We would be able to sell all five houses to one big corporate customer, and we had already spoken to a property dealer who was trying to find a buyer in order to get a good commission.

That was going to be my biggest break. I had asked the boys to look for a large tract of land on the outskirts of the city where we could develop our own set of buildings, blocks of storey houses and upscale apartments. Things were going according to plan, and I was quietly excited. However, things were not going so well regarding my relationship with Abena.

My buddies Ebo and Nana Kwame had called to say that they met Abena and her friend Jennifer enjoying lunch with a guy, and Ebo believed that Jennifer was ‘promoting’ an affair between Jennifer and the guy. They were of the view that the promotion seemed to be going in the guy’s favour, because only an agricultural extension worker in the north who did not have the resources to take care of a beautiful girl like her.

And apart from being wealthy, the guy comes from an influential family, so Abena had done much better leaving a miserable civil servant like you for him.

“As I’ve already said, I will stop by her place, but I will mind my own business from now. Hey, let’s talk family. How are our parents? And my brothers-in-law? And my nephews and nieces? Why don’t we meet on Sunday? I’m going to drop my bags at my place, and go to see Mama and Dad.”
