Explanation: 

Detailed explanation-1: -GABA is an inhibitory neurotransmitter in the CNS that reduces neuronal excitability and regulates muscle tone. GABA is involved in pain modulation by regulating the transmission of nociceptive signals through the activation of GABA receptors located on primary afferent terminals and in the dorsal horn [88].

Detailed explanation-2: -The function of a neuron is to transmit nerve impulses along the length of an individual neuron and across the synapse into the next neuron. The electrical signals transmitted by neurons are called action potentials. The electrical signal needs to cross the synaptic gap to continue on its journey to, or from, the CNS.

Detailed explanation-3: -Neurotransmitters are important in boosting and balancing signals in the brain and for keeping the brain functioning. They help manage automatic responses such as breathing and heart rate, but they also have psychological functions such as learning, managing mood, fear, pleasure, and happiness.

Detailed explanation-4: -A STIMULUS is a change in the environment that may be of sufficient strength to initiate an impulse.
