Neuro-science
Psychobiology

Psychobiology
The field of psychology concerned with the neural and biochemical bases of behavior and mental processes
Neuro-psychology
Purpose of nervous system
To gather and process information
Produce responses to stimuli
Coordinate the working of the different cells
2 interrelated divisions of the nervous system
Central N.S.
Peripheral N.S.
Made up of the brain and the spinal cord
Central nervous system
Which connects the brain and the spinal cord to everything else in the body such as the sense organs muscles and glands
Peripheral nervous sytem
Is a large rope like segment of nerve tissue extending down the vertebral column
Spinal cord
Are simple, inborn, automatic responses of some parts of the body.
Reflexes
Also known as the startle reflex, is one of the infantile reflexes
Moro reflex
O e of the infantile reflexes. It is normal in children up to 2 yrs old, but it disappears just as the child ages and the nervous system becomes more developed
Babinski reflex
Os the reduction of the pupil in size in response to light
Pupillary reflex
Protected by the skull, is the organ of our body that most directly controls our thoughts, emotions, and motivation
Brain
Core of the brain
Hindbrain
Forebrain
Midbrain
Hindbrain
Medulla oblongata
Pons varoli
Cerebellum
It plays an important role in autonomic activities
Medulla oblongata
Made up largely by nerve fibers that connect higher and lower levels of the nervous system
Pons varoli
Role is to maintain posture and to smooth out coordinate complex muscular activities
Cerebellum
Serves as the link between hindbrain and forebrain, and has a special role in audio and auditory activities
Midbrain
Composes of two large cerebral hemispheres and a number of important structures within the central regions of the hemispheres
Forebrain
Forebrain
Thalamus
Hypothalamus
Cerebrum
