Central Nervous System (CNS)
The CNS is divided into the brain and spinal cord.
Cranial Nerves
There are 12 pairs of cranial nerves arising from the brain.
Blood Brain Barrier (BBB)
A selective permeability barrier that inhibits certain substances from entering the CNS.
Neurotransmitters
Chemicals that transmit signals across a synapse from one neuron to another.
GABA
An inhibitory neurotransmitter that decreases excitability in the CNS.
Action Potential
A rapid rise and fall in voltage across a cellular membrane.
Tricyclic Antidepressants (TCAs)
Antidepressants that work by inhibiting the reuptake of norepinephrine and serotonin.
Selective Serotonin Reuptake Inhibitors (SSRIs)
Antidepressants that increase serotonin levels by blocking its reabsorption into neurons.
Benzodiazepines
A class of medications that increase the frequency of opening of the GABA-A receptor channel.
Lithium
A mood stabilizer used for treating bipolar disorder by affecting various neurotransmitter pathways.
Generalized Anxiety Disorder (GAD)
A psychological condition characterized by excessive worry and anxiety over six months.
Pharmacological Therapy for Epilepsy
Treatment strategies that aim to decrease excessive neuronal discharge and prevent seizure propagation.
Barbiturates
Sedative drugs that increase the duration of opening of the GABA receptor channel.

Sedative drugs that increase the duration of opening of the GABA receptor channel.
Peripheral Nervous System (PNS)
The PNS consists of nerves and ganglia outside the brain and spinal cord, connecting the CNS to the rest of the body.
Synapse
The junction between two neurons where electrical or chemical signals are transmitted.
Dopamine
A neurotransmitter involved in reward, motivation, motor control, and pleasure.
Serotonin
A neurotransmitter that regulates mood, appetite, sleep, and cognitive functions.
