How the Brain Works
Overview Ways of Studying the Brain How is the Brain Organized?
Studying the Brain Autopsy EEG and evoked potentials Brain Imaging – fMRI – PET
Hindbrain Pons: connects spinal cord and brain Medulla: controls vital functions Cerebellum: plans and monitors movement
The Cerebrum Four lobes Limbic system Cortex is outer surface
Thalamus: organizes sensory information Hypothalamus: regulates body states Hippocampus: forms memories Amygdala: controls emotions The Limbic System
The Four Lobes Occipital: vision Temporal: hearing, language Frontal: personality, thinking, motor control Parietal: touch, temperature, pain
Cerebral Cortex Highly organized motor cortex: strip of frontal lobes that generates commands for movement somatosensory cortex: strip of parietal lobes that processes touch information
The Two Hemispheres Similar, but not identical in structure or function Most nerve fibers cross to the other side of the brain Right hemisphere controls left side of body, and vice versa
Left Brain-Right Brain Left Hemisphere specialized for language, logic, math Right Hemisphere specialized for spatial ability, music, art True for almost all right-handers and many left-handers.

Neuroscience and the Brain. Cerebral Cortex and Hemispheres Cerebral cortex: outermost layer of the brain Spread out all the wrinkles-cerebral cortex.
What part of the brain is a relay station for sensory information?
And Brain Organization
Consists of the brain stem pathway for all nerves entering and leaving the brain The Pons-- involved with sleep and alertness; connects brain.
The Human Brain.
The Brain Module 08. Lower - Level Brain Structures brainstem: oldest, most basic part of brain medulla – controls life-support functions like breathing.
The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebrum controls.
The Brain Divided into two hemispheres Mirror images in structure Connected mainly by corpus callosum Sensory and motor functions are contra-lateral.
Objectives 31.2 The Central Nervous System
The Meninges Dura mater - outermost layer Arachnoid mater - no blood vessels, in between layer (resembles a spider web) Pia mater -inner membrane, contains.
The Human Brain. The Central Core Cerebellum: Motor Control Brain Stem: Pons: Sleep, arousal Reticular Formation: Sleep, arousal, attention
Cognitive Neuroscience z What do neurons have to do with cognition? z How can neurons do complex things? z How do we know how the brain works? z What.
The Brain How is the brain structured? How are the parts connected?
BIOLOGICAL BASES OF BEHAVIOR Questions What does Biology have to do with Psychology? How does the brain produce behavior?
Studying The Brain.
Inside the Human Brain HSP3M. Inside the Teenage Brain Adolescence is characterized by extreme mood swings and participation in risk-taking behaviour.
THE HUMAN BRAIN. 3.5 pounds of gelatinous material at the root of everything we do/are.
