GABA, the principal inhibitory transmitter excites immature neurons in all animal species studied. This is due to the higher intracellular concentration of chloride at early developmental stages. Excitatory actions of GABA play an important action in brain maturation. Recent observations also suggest an abrupt shift during delivery that exerts a neuro-protective action contributing to reduce the sequels of trauma and anoxic episodes. These observations have important clinical implications in relation to delivery associated insults but also preterm delivery and more generally consumption of agents during gestation.

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.
Gut-Brain Axis01:22

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...

Antiepileptic Drugs: GABAergic Pathway Potentiators

γ-aminobutyric acid or GABA, plays a pivotal role as an inhibitory neurotransmitter in the brain. GABA pathway potentiators, also known as GABAergic drugs, are a class of pharmaceutical agents designed to enhance the functioning of the GABAergic system. These medications primarily treat epilepsy, a neurological disorder characterized by recurrent seizures.
The key GABA pathway potentiators used in epilepsy management are as follows.
Benzodiazepines are a well-known class of drugs used for their...
