Study Notes
- Structural neuroplasticity refers to changes in the physical structure of the nervous system, such as neuronal morphology, synaptic connectivity, and gene expression.
- Functional neuroplasticity concerns the changes in the activity and connectivity of neurons and circuits at the molecular and system levels.
- The central nervous system (CNS) has a high degree of structural invariability, which ensures stability of neural circuits and protects specificity of neural connections. However, it has a low capacity for regeneration and repair.
- Neuroplasticity, which includes adaptive behavior, learning, memory, and recovery after injury, occurs at different levels, from molecules and interactions to cellular networks and synaptic plasticity.
- Hebbian plasticity is a process of strengthening synaptic connections between neurons with correlated activity, which is crucial for encoding and retaining memories.
- Homeostatic plasticity compensates for changes in synaptic strength by altering neurotransmitter release and controlling the abundance of postsynaptic receptors.
- The older brain is more plastic than previously thought, with changes in white matter and cortical regions in response to learning and experience.
- The morphology of dendritic spines in the brain differs between healthy individuals and those with neuropsychiatric disorders such as schizophrenia, depression, and alcohol abuse.
- Transcranial magnetic stimulation (TMS) is a non-invasive technique that can induce neuroplasticity by stimulating specific areas of the brain, potentially providing a therapeutic intervention for various neurological and psychiatric conditions.
- Impaired neuroplasticity in the dorsolateral prefrontal cortex has been linked to alcohol abuse, depression, and aging.
- Anodal transcranial direct current stimulation (atDCS) can improve performance in older adults on cognitive tasks and enhance neuroplasticity in the prefrontal cortex.
- Psychedelics such as LSD, psilocybin, and DMT have been shown to promote neuroplasticity and have potential therapeutic applications in treating mental health disorders.
