Plasticity

Dr. Rishabh Pathak

Plasticity refers to the brain's ability to reorganize itself by forming new neural connections throughout life in response to experiences, learning, and environmental stimuli. This adaptive capacity allows the brain to change its structure and function in order to optimize performance, recover from injury, and adapt to new challenges. Plasticity is a fundamental property of the nervous system that underlies learning, memory, and various cognitive processes.


There are two main types of plasticity in the brain:


1. Structural Plasticity: Structural plasticity involves changes in the physical structure of the brain, such as the formation of new synapses (connections between neurons), the growth of dendrites (branch-like extensions of neurons), and the reorganization of neural circuits. Structural changes in the brain occur in response to learning, environmental enrichment, and sensory experiences. For example, practicing a new skill can lead to the formation of new neural connections and the strengthening of existing ones, enhancing the brain's ability to perform that skill.


2.  Functional Plasticity: Functional plasticity refers to changes in the functional organization of the brain, including alterations in neural activity patterns and the recruitment of different brain regions for specific tasks. Functional plasticity allows the brain to adapt its processing strategies in response to changing demands and experiences. For instance, after a brain injury, other areas of the brain may compensate for the damaged region by taking on new functions, demonstrating the brain's ability to reorganize and adapt to maintain cognitive abilities.


Plasticity is most pronounced during critical periods of development, such as early childhood, when the brain is highly malleable and responsive to environmental influences. However, plasticity continues throughout life to a certain extent, allowing for ongoing learning, memory formation, and adaptation to new experiences.


Factors that influence brain plasticity include sensory stimulation, motor activities, social interactions, cognitive challenges, and environmental enrichment. By understanding and harnessing the principles of plasticity, researchers and clinicians can develop interventions to promote healthy brain development, enhance cognitive function, and facilitate recovery from brain injuries or neurological disorders.

 

Having a strong interest in research, I began my work as a physiotherapist and went on to earn a master's degree in the field, specializing in neurology. I also finished a few post-graduation diplomas in between and with persistence. Research has always been a passion of mine, both for the advancement of my career and my personal life. A major factor in reaching my goals is education. Although my first bachelor's thesis was in the innovation area, I had been exposed to research work even in my informal school days. I always like working on creative initiatives and taking an interest in other people's experiences. The saying, "Healthy criticism is a way to learn more and more about your flaws to make them rectified," is true, in my opinion. In this way, we may hone our abilities and create a growth-oriented vision for both our personal and professional career pathways. I am thus constantly willing to learn and advance in my work. Additionally, I think that "it is in our hands to terminate our lives with a brand-new ending if we are unable to originate our lives with a brand-new start."

Neural Circuits and Computation

Dr. Rishabh Pathak

  Neural circuits and computation refer to the intricate networks of interconnected neurons in the brain that work together to process information and generate behaviors. Here is a brief explanation of neural circuits and computation: 1.  Neural Circuits : Neural circuits are pathways formed by interconnected neurons that communicate with each other through synapses. These circuits are responsible for processing sensory information, generating motor commands, and mediating cognitive functions. 2.   Computation in Neural Circuits : Neural circuits perform computations by integrating and processing incoming signals from sensory inputs or other neurons. This processing involves complex interactions between excitatory and inhibitory neurons, synaptic plasticity, and feedback mechanisms. 3.   Behavioral Relevance : Neural circuits play a crucial role in mediating specific behaviors by translating sensory inputs into motor outputs. Different circuits are specialized for various functions, su

How do NTN and Lmx1α influence the Notch signaling pathway during this differentiation process?

  In the differentiation of human bone marrow mesenchymal stem cells (h-BMSCs) into dopaminergic neuron-like cells, NTN (Neurturin) and Lmx1α (LIM homeobox transcription factor 1 alpha) play a significant role in influencing the Notch signaling pathway. The study discussed in the PDF file investigated the impact of NTN and Lmx1α on the differentiation process and the associated changes in Notch-related gene expression. 1. Neurturin (NTN):    - Neurturin is a neurotrophic factor that belongs to the glial cell line-derived neurotrophic factor (GDNF) family. It has been shown to promote the survival and differentiation of dopaminergic neurons.    - In the study, h-BMSCs overexpressing NTN were induced to differentiate into dopaminergic neuron-like cells. The presence of NTN likely influenced the expression of Notch-related genes, leading to changes in the Notch signaling pathway during differentiation.   2. LIM homeobox transcription factor 1 alpha (Lmx1α):    - Lmx1α is a trans

Are there any potential side effects or limitations to consider when using Vitamin C as a treatment for malignant melanoma?

  When using Vitamin C as a treatment for malignant melanoma, it is important to consider potential limitations and side effects. Some limitations include the lack of in vivo factors in in vitro studies, which may not fully represent biological interactions in real patients. Additionally, the studies mentioned in the review article were conducted in stimulating environments rather than in actual patients, which could affect the translation of results to clinical practice. As for side effects, while Vitamin C has shown promising anti-tumor effects in melanoma cells, further research is needed to fully understand its efficacy and safety in real patients. It is crucial to conduct more studies to investigate Vitamin C's role in transforming the genetic nature of melanoma and to evaluate its potential side effects when used as an adjuvant therapy.
