PSY 200 Test #1 The Brain
Computerized Tomography Scan(CT Scan)
Multiple x-rays are shot from many different angles, and the computer combines the readings to create a vivid image of horizontal slice of the brain.
(Positron Emission Tomography) PET Scan
Examines brain function, mapping actual activity in the brain over-time
Magnetic Resonance Imaging (MRI)
Uses magnetic fields, radio waves, and computerized enhancement to map out brain structure.
Functional Magnetic Resonance Imaging (fMRI)
Monitors blood flow and oxygen consumption in the brain to identify area's of high activity- High resolution.
Includes the cerebellum, medulla, and the pons
Structure that coordinates fine muscle movement/ balance
Responsible for regulating largely unconscious functions such as breathing and circulation of blood.
Involved in sleep and arousal
Lies between the hindbrain and forebrain- Integrates sensory processes such as vision and hearing.
Runs through both the hindbrain and midbrain- Contributes to the modulation of muscle reflexes, breathing, and pain perception.
Includes the thalamus, the hypothalamus, the limbic system, and the cerebrum
Structure in which all sensory information must pass to get to the cerebral cortex- handles incoming and outgoing signals
Responsible for regulating basic biological needs: hunger, thirst, temperature control.
A network of hormone producing glands
Involved in the regulation of emotion, memory, and motivation.
Part of limbic system involved in learning and memory.
Part of limbic system involved in learning and memory
Part of limbic system involved in emotion and aggression.
Responsible for sensing, thinking, learning, emotion, consciences, and voluntary movement.
Band of fibers that is the communication bridge between the right and left halves of the brain.
At the back of the head- Includes the cortical area where most visual signals are sent and visual process is begun.
Forward of the occipital lobe- includes the area that registers sense of touch (primary somatosensory cortex). Also involved in integrating visual input and monitoring body's position in space.
Primary Somatosensory Cortex (sensory cortex)
Sense of touch- various sections of this area recieve signals from different regions of the body
Below the parietal lobe- Deals with auditory processing
At front- Contains the primary motor cortex(motor cortex) which controls movement of muscles. Contains prefrontal cortex.
Involved with working memory, memory for sequences of events, and reasoning about relations between objects and events.
Responsible for transmitting information between brain and rest of body- handles simple reflexes
Controls movement of muscles.
Master gland that regulates other endocrine glands.
Peripheral Nervous System
Made up of all the nerves that lie outside the brain and spinal cord. Subdivided into the Somatic nervous system and Autonomic nervous system.
Somatic Nervous System
Made up of nerves that connect to voluntary skeletal muscles and to sensory receptors.
Afferent Nerve Fibers
Axons that carry information inward to the central nervous system.
Efferent Nerve Fibers
Axons that carry information outward from the central nervous system.
Autonomic Nervous System
Made of nerves that connect to the heart, blood vessels, smooth muscles, and glands. (You feel someone is following you- heart rate and breathing increases)
Central Nervous System
Consists of the brain and the spinal cord.
Protective sheaths covering the brain and spinal cord.
Branch of the autonomic nervous system that conserves bodily resources.
Branch of the autonomic nervous system that mobilizes resources for emergencies.
Involved in speech production
Involved in language comprehension.
