The reticular formation is a network of neurons located in the brainstem. It is involved in regulating arousal, attention, and sleep-wake cycles.
The cerebellum (the part of the brain that processes movement) has clear pathways to the parts of the brain involved in memory, attention, spatial perception, language, complex emotional behavior, and decision making.
The pons is the part of the brain that regulates body movement, attention, sleep, and alertness. The pons is the part of the brainstem that links the medulla oblongata and the thalamus.
Hippocampus
Hypothalamus
The optic nerves connect the brain and eyes.
The frontal cortex--the part of the brain that is heavily involved in tasks such as task-management and inhibition.
The lobes in the back of the brain called the occipital lobes.
No single part of the brain is responsible for consciousness. The brainstem, diencephalon, and cerebral hemispheres are all involved in consciousness.
The prefrontal cortex, particularly the dorsolateral prefrontal cortex and anterior cingulate cortex, are believed to be the key regions of the brain involved in awareness. These areas play a critical role in higher-order cognitive functions such as self-awareness, attention, and decision-making.
The locus coeruleus is a nucleus in the pons. The name means "dark spot". The pons is part of the brain stem. It produces norepinephrine along with the adrenal medulla. It is involved in anxiety, attention, memory and emotions.
The prefrontal cortex is the part of the brain that primarily controls concentration. It is responsible for executive functions, including focusing attention, filtering distractions, and maintaining sustained attention on tasks.
