The cerebrum is the seat of voluntary reflexes. They are formed on the basis of involuntary reflexes. Are acquired during life through learning (memory, repetition, drop). Example: a child who often consume food that he liked to spit at the sight, smell or thought of that food.
Explanation: The cortex is making repeated connections between nerve centers and they command salivary center in the brainstem.
Other involuntary reflexes:
- a musical instrument.
Conscious voluntary reflexes are acquired during life, belong to the individual may forget or erase the neexersare have only cortex nerve center. A chain of voluntary forms an automatic reflex.
The cortex are 3 types of areas:
- sensitive areas
- motor areas
- association areas.
Receive information from the outside sensitive areas and develops specific sensations. They are located in lobes: temporal area (auditory and olfactory area), parietal area (area gstativa and skin sensitivity), occipital (visual area). Areas-creierului1
Motor areas analyzes, selects and prepares orders sent to effectors. Pathways are driving descending white matter bundles. Motor areas are located in the frontal lobe.
The areas of activity of the other areas and association analyzes performed complex mental processes (attention, thinking, logic, memory ratio, imagination). They are located in all lobes.
First signaling system of the body: all incoming signals in the environment that triggers reactions. The second signaling system: language (human specific).
