Functions of Cerebrum

 (RED PART IS CEREBRUM)

Intro  : The cerebrum or telencephalon is a large part of the brain containing the cerebral cortex (of the two cerebral hemispheres), as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system. 

Functions : 

The cerebrum is a major part of the brain, controlling emotions, hearing, vision, personality and much more. It controls all precision of voluntary actions.It functions as the center of sensory perception, memory, thoughts and judgement; the cerebrum also functions as the center of voluntary motor activities. 

According to lobes : 

• Frontal Lobe : 

   frontal lobe)

The frontal lobe is where “executive functions,” such as the regulation and expression of emotions, language, reason, problem-solving, sexuality, and planning take place.

The frontal lobe is the center of higher functions that separate humans from all other species, giving us the ability to communicate and form rational thoughts in a way that is not yet physiologically possible for other species.

• Parietal Lobe : 

  Parietal lobe 

• This portion of the brain is responsible for taking in and interpreting tactile sensory information: touch, temperature, pressure, and pain. This area of the brain also controls the ability to taste – so next time you snap a photo of your meal for Insta, make sure to tag your parietal lobe and give it props.

• Temporal Lobe 

  Temporal lobe 

The primary auditory cortex is located within this lobe and receives sensory information related to hearing. The actual sensation of hearing and the processes by which we interpret auditory information (directional source of a sound, what type of sound, etc.) are controlled here. Recognition of language also takes place here.

• Occipital Lobe : 

  Occipita lobe 

The occipital lobe is central to visual processing. Interpretation of visual stimuli requires the ability to analyze information including depth, distance, location, light/color, and identity of the object being observed.

According to the system.

• Sensory processing : The primary sensory areas of the cerebral cortex receive and process visual, auditory, somatosensory, gustatory, and olfactory information. Together with association cortical areas, these brain regions synthesize sensory information into our perceptions of the world.

Olfaction : The olfactory bulb, responsible for the sense of smell, takes up a large area of the cerebrum in most vertebrates. However, in humans, this part of the brain is much smaller and lies underneath the frontal lobe.

• communication :Speech and language are mainly attributed to the parts of the cerebral cortex. Motor portions of language are attributed to Broca's area within the frontal lobe. Speech comprehension is attributed to Wernicke's area, at the temporal-parietal lobe junction.

•  Learning and memory : Memory formation is attributed to the hippocampus and associated regions of the medial temporal lobe.
