The cerebellum (located at the back of the head near the nape of the neck) is responsible for balance and muscle coordination. It's the area that allows your baby to progress from rolling over to crawling and then to walking.
This area also coordinates motor and sensory functions. In other words, it combines signals from all of your baby's senses to help her figure out what she's feeling when she moves around.
The cerebellum also helps with higher brain functions, such as learning music and language. And some researchers believe the cerebellum may play a critical role in the way children process social cues, which could help explain the cause of autism (a developmental disorder associated with communication and social impairment).
difficult for the individual to moderate his/her emotional reactions
= significant effect on how the individual interacts with others
- social relationships are difficult
= he/she never appropriately develops empathy or feelings of guilt
= acts more impulsively without regard for the consequences
The temporal lobe serves several processing functions in the brain that mainly deal with organization of sensory input: it processes sound in the primary auditory cortex and the semantics of speech and vision. It also contains the hippocampus, which is involved with long-term memory and spatial awareness. The amygdala is also located in the temporal lobe, which processes emotions and memories. All these functions are important in studying temporal lobe epilepsy since they are affected in several ways during a temporal lobe seizure. Damage, specifically in the hippocampus, often occurs after a temporal lobe seizure.
The occipital lobe is the rear portion of the cerebral cortex , located at the lower back of the head. These lobes:
- receive and process visual information
- contain areas that help in perceive in shape and colors.
Damage to them may cause deformation of the visual field and of perception of size, color and shape.
- Defects in vision (Visual Field Cuts)
- Difficulty with locating objects in environment
- Difficulty with identifying colors (Color Agnosia)
- Production of hallucinations Visual illusions - inaccurately seeing objects
- Word blindness - inability to recognize words
- Difficulty in recognizing drawn objects
- Inability to recognize the movement of an object (Movement Agnosia)
- Difficulties with reading and writing
The occipital lobes are the center of our visual perception system. In this brain region is visual information processing. Information from the eyes come in here and be processed.
Here, the information comes in by two major streams: the ventral stream and the dorsal stream. Both information flows are then sent to the frontal lobe there to penetrate into consciousness.
