To solve the problem, we need to identify the part of the brain responsible for controlling **emotions**.
1. Understanding Brain Functions:
- The Cerebrum is the largest part of the brain and is responsible for higher brain functions such as thinking, decision-making, memory, emotions, and voluntary movements.
- The Diencephalon includes structures like the thalamus and hypothalamus and is involved in sensory and autonomic functions.
- The Midbrain controls eye movement and processes visual and auditory information.
- The Cerebellum controls balance and coordination of voluntary movements, not emotions.
2. Emotional Control:
Emotions are primarily regulated by the limbic system, which is a part of the cerebrum.
Final Answer:
Loss of emotional control is due to malfunction of the \( {\text{Cerebrum}} \).
Choose the correct option:
Statement I: Synaptic transmission occurs from presynaptic to postsynaptic neuron.
Statement II: Presynaptic membrane contains receptors for neurotransmitters.
