Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Gut-Brain Axis

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...

Neurotransmitters

Neurotransmitters

Neurotransmitters are essential chemical messengers within the nervous system, facilitating the communication between neurons. These chemical messengers, varying in function and effect, are critical for sustaining various aspects of neurological health and emotional well-being.

Neuroplasticity

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Causes of Social Behavior III: Biological and Environmental Influences

Causes of Social Behavior III: Biological and Environmental Influences

Social behavior is a complex phenomenon that arises from the interaction between biological predispositions and environmental influences. This intricate interplay shapes how individuals think, feel, and act in various social contexts. Understanding these mechanisms requires insights from psychology, neuroscience, genetics, and evolutionary theory.Environmental Influences on Social BehaviorEnvironmental factors, including temperature, odors, and visual stimuli, play a crucial role in shaping...

Summary

This summary is machine-generated.

Adult neurogenesis, the birth of new brain cells, is regulated by the immune system. Immune cells can either harm or support this process, impacting learning and memory.

Neuroscience
Immunology
Cell Biology

Background:

Adult neurogenesis, the continuous production of new neurons in specific brain regions like the hippocampus, was once thought impossible.
The precise functional role of these new neurons in cognition and brain maintenance remains under investigation.

Purpose of the Study:

To review the current understanding of how the immune system influences adult hippocampal neurogenesis.
To explore the dual role of immune cells (microglia) in either supporting or inhibiting neurogenesis based on their activation state.

Main Methods:

Review of existing scientific literature on adult neurogenesis and neuroinflammation.
Analysis of the impact of different immune cell phenotypes on neural stem cell proliferation, survival, and function.

Main Results:

Immune activation, particularly by microglia with an inflammatory phenotype, can reduce the proliferation, survival, and function of new neurons.
Microglia with a protective phenotype can support adult neurogenesis.

Conclusions:

The immune system plays a critical role in regulating adult hippocampal neurogenesis.
Inflammation-induced reductions in neurogenesis may contribute to cognitive deficits, highlighting the need to understand immune regulation for potential therapeutic interventions.
