Concept
Neurotrophic factors are a family of proteins crucial for the development, survival, and function of neurons in the nervous system. They play a significant role in neural plasticity, repair, and regeneration by promoting neuronal growth and protecting against cell death.
Concept
Ischemic preconditioning is a protective mechanism where brief episodes of ischemia make the heart or other tissues more resistant to a subsequent prolonged ischemic event. This phenomenon reduces tissue damage and improves recovery by activating various cellular pathways that enhance survival and repair processes.
Concept
Synaptic transmission is the process by which neurons communicate with each other through the release and reception of neurotransmitters across a synapse. This fundamental mechanism underlies all neural activity and is essential for brain function, including learning, memory, and behavior.
Concept
Glutamate toxicity, also known as excitotoxicity, occurs when excessive levels of the neurotransmitter glutamate overactivate receptors, leading to neuronal injury and cell death. This process is implicated in various neurodegenerative diseases, including Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis (ALS).

Optic nerve damage refers to harm inflicted on the optic nerve, which can lead to vision loss or blindness, often resulting from conditions like glaucoma, trauma, or inflammation. Early detection and treatment are crucial to prevent irreversible damage and preserve vision.
Concept
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the brain and spinal cord that acts as a cushion to protect the central nervous system while also removing waste products. It plays a crucial role in maintaining intracranial pressure and serves as a medium for nutrient exchange between the blood and nervous tissue.
