Definitions:

Dendritic Arborization

Dendritic arborization refers to the complex branching pattern of dendrites in neurons, which allows for the reception of signals from other neurons and is crucial for neural connectivity and communication.

Glial Cells

Non-neuronal cells in the central and peripheral nervous system that provide support and protection for neurons, also playing a role in signal transmission.

Electroconvulsive Therapy

Electroconvulsive therapy (ECT) is a medical treatment which involves inducing seizures in patients under general anesthesia to provide relief from severe mental illnesses, notably major depressive disorder and bipolar disorder.

Brain-Derived Neurotrophic Factor

Brain-Derived Neurotrophic Factor (BDNF) is a neurotrophin involved in the survival, development, and plasticity of neurons in the central and peripheral nervous systems.
