Description. Arousal, blood pressure, heart rate, respiratory rhythms, the sleep-wake cycle, sensation, motion, and the perception of pain are all controlled and synchronized by the brain stem.
What are 4 functions of the brain stem?
The brainstem has many basic functions, including regulation of heart rate, breathing, sleeping, and eating. It also plays a role in conduction. All information relayed from the body to the cerebrum and cerebellum and vice versa must traverse the brainstem.
How does the brainstem affect behavior?
A recent study reveals how gene control mechanisms define the identity of developing neurons in the brainstem. The researchers also showed that a failure in differentiation of the brainstem neurons leads to behavioral abnormalities, including hyperactivity and attention deficit.
What behaviors does the brainstem control?
All told, it appears that the brainstem contains CPGs for breathing, chewing, suckling, licking, swallowing, and whisking, with one on each side (left and right sides), total of ten CPGs, located within or nearby regions of the medullary IRt.

What part of the brainstem controls arousal?
Brainstem arousal circuits
The basal forebrain contains cholinergic, glutamatergic, and GABAergic neurons that promote arousal via inputs to the cerebral cortex.
Does the brainstem control fear?
These neurons project to an area of the brainstem, known as the midbrain periaqueductal gray (PAG), that controls the fear response.
Do emotions originate in the brain stem?
Emotions trickle down to the body from the hypothalamus through either it’s neuronal connections to the brain stem or by way of the secretions of the pituitary gland.
What part of the brain controls emotions and memory?

What is the anger hormone called?

Anger causes a physical reaction in the body. It releases adrenaline, the “fight-or-flight” hormone that prepares a person for conflict or danger. This can have the following effects: a rapid heartbeat.
What organ gets affected by anger?
The adrenal glands flood the body with stress hormones, such as adrenaline and cortisol. The brain shunts blood away from the gut and towards the muscles, in preparation for physical exertion. Heart rate, blood pressure and respiration increase, the body temperature rises and the skin perspires.
What hormone is responsible for crying?
Biologically, there may be a reason women cry more than men: Testosterone may inhibit crying, while the hormone prolactin (seen in higher levels in women) may promote it.
