Area of Science:

  • Neuroscience
  • Developmental Biology
  • Cellular Biology

Background:

  • Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the adult central nervous system (CNS), regulating glutamatergic activity.
  • In the immature CNS, GABA functions as an excitatory transmitter and a trophic factor crucial for brain development.
  • GABAergic transmission is implicated in higher cognitive functions, including memory, learning, and anxiety.

Purpose of the Study:

  • To investigate the developmental changes in the GABAergic transmission system.
  • To identify key factors involved in the formation of GABAergic synapses and networks.
  • To understand how GABA influences developing neurons and forms functional synapses in the cerebellum.

Main Methods:

  • Morphological investigation of developmental changes.
