The human brain is a complex organ responsible for cognition, emotions, and control of bodily functions. It consists of billions of neurons interconnected through synapses, forming the basis of consciousness and intelligence.
Given below are some disorders noticed in some patients. It could it be due to malfunctioning of which part of brain: a) Loss of sensation of feeling full b) Lowered ability to salivate c) Difficulty in maintaining the posture and balance in body

The areas of the brain responsible for sensation, posture, and balance are interconnected and involve several structures. Key regions implicated in these functions include:
Cerebellum: Located at the back of the brain, the cerebellum plays a crucial role in motor control, coordination, and balance. Damage to the cerebellum can result in problems with posture and coordination.
Vestibular System: Found within the inner ear, the vestibular system contributes to balance and spatial orientation. Disorders affecting the vestibular system can lead to dizziness, vertigo, and difficulties with balance.
Somatosensory Cortex: Situated in the parietal lobe, the somatosensory cortex processes sensory information from the body, including touch, temperature, and proprioception (awareness of body position). Disorders impacting this area can affect sensations and spatial awareness.
Brainstem: The brainstem, particularly the medulla and pons, is involved in regulating basic bodily functions, including posture and balance. Damage to the brainstem can result in a range of motor and sensory issues.
Disorders affecting these brain regions or the connections between them can lead to disturbances in sensation, posture, and balance. Conditions such as cerebellar disorders, vestibular disorders, and certain types of neuropathies can manifest with symptoms related to these functions. Diagnosing and treating such disorders often involve a multidisciplinary approach, including neurology, physical therapy, and sometimes medication.
The mentioned disorders may be associated with malfunctioning of specific parts of the brain. Here are the likely regions responsible for each disorder:
a) Loss of sensation of feeling full:
This symptom is often associated with the hypothalamus. The hypothalamus, located in the brain, plays a crucial role in regulating appetite and satiety. Dysfunction in this area can lead to disruptions in the signals related to hunger and fullness.
b) Lowered ability to salivate:
The ability to salivate is controlled by the salivary nuclei in the brainstem. Dysfunction in this region, particularly in the cranial nerve nuclei responsible for salivary gland control, can lead to a reduced ability to salivate. These nuclei are located in the medulla oblongata and pons, which are parts of the brainstem.
c) Difficulty in maintaining posture and balance in the body:
The coordination of posture and balance is primarily regulated by the cerebellum. The cerebellum, located at the back of the brain, is involved in the fine-tuning of motor movements and maintaining equilibrium. Dysfunction in the cerebellum can result in problems with coordination, posture, and balance.
