By the age of 7, our brains are 95 percent of their adult size.The brains of 2-year-olds consume twice as much energy as do .that is amazing.
How are visual areas of the brain connected to motor areas for the sensory guidance of movement? the answar is that Visual areas of the brain must be connected to motor areas for the sensory guidance of movement. The first step in the pathway from the primary visual cortex is by way of the dorsal stream of visual areas in the parietal lobe. The fact that monkeys can still guide their limbs visually after cortico-cortical fibres have been severed suggests that there are subcortical routes that link visual and motor areas of the brain. The pathway that runs from the pons and cerebellum is the largest of these. Pontine cells that receive inputs from visual cortical areas or the superior colliculus respond vigorously to appropriate visual stimuli and project widely on the cerebellar cortex. A challenge for future research is to elucidate the role of these cerebellar target areas in visuo-motor control.
Your brain is your most powerful organ, yet weighs only about three pounds. It has a texture similar to firm jelly.
It has three main parts:
The cerebrum fills up most of your skull. It is involved in remembering, problem solving, thinking, and feeling. It also controls movement.
The cerebellum sits at the back of your head, under the cerebrum. It controls coordination and balance.
The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.
