Explanation:

Question 14

To determine the major inhibitory neurotransmitter in the brain, we analyze each option:

• GABA (gamma - aminobutyric acid) is known to be the major inhibitory neurotransmitter in the brain.
• Glutamate is an excitatory neurotransmitter.
• Dopamine is involved in reward, motivation, etc., and is not the major inhibitory one.
• Acetylcholine is involved in muscle movement and cognitive functions, not the major inhibitory neurotransmitter.

To find the correct term for bundles of interconnected neurons that fire in synchrony:

• Nerves are bundles of axons in the peripheral nervous system, not about neurons firing in synchrony in the context of interconnected neuron bundles in the brain.
• Networks are bundles of interconnected neurons that fire in synchrony.
• Glia are support cells for neurons, not neuron bundles.
• Ganglia are clusters of neuron cell bodies in the peripheral nervous system.

To determine the role of the occipital lobe in the visual process:

• The visual cortex is located in the occipital lobe, and it is responsible for processing visual information. Processing cues from the thalamus is not the main role of the occipital lobe in the visual process (the thalamus relays visual information to the occipital lobe, but the occipital lobe's main role is being the site of the visual cortex). The fovea is in the retina, and the retina is in the eye, not the occipital lobe.
• So the occipital lobe is the site of the visual cortex.

Answer:

A. GABA
