Brain Parts Flashcards
Limbic System
Regulates emotion, memory, motivation.
Thalamus, hypothalamus, amygdala, hippocampus
Thalamus
Collects/ integrates sensory info to send to other brain areas
The “gateway”
Hypothalamus
Master regulatory structure
Basic biological needs- FOUR Fs
Hippocampus
Creation of new memories VIA new neuron connections
Amygdala
Associates things in world with certain emotional responses.
MAIN RAGE AND FEAR
Spinal chord
Brain body communication
Hind Brain
Basic survival functions
Medulla, Pons, and Cerebellum
Mid Brain
Movement
Contains neurons that release dopamine
Contains reticular formation
Reticular Formation
Reflexes, breathing, pain, sleep, arousal, communication WITHIN brain
Medulla
Heartbeat, breathing, reflexes
Pons
Sleep and arousal
Cerebellum
Voluntary movement, coordination, non-verbal learning and memory
Basal Ganglia
Planning/producing/controlling movement, determines course of action once SENSORY info passes through primary (cortex?) and sends to motor cortex
Corpus callosum
Connects left and right hemispheres
FOUR LOBES?
Parietal, Occipital, Temporal, Frontal
Parietal Lobe
Primary sensory cortex
-receives sensory info
Occipital Lobe
Primary Visual Cortex
-receives visual info
Temporal Lobe
Primary auditory cortex (hearing)
Autobiographical memory
Wernickes Area- Processes speech and language
Fusiform face area- facial recognition
Wernickes area
Processes speech and language
Fusiform face area
Facial recognition
Frontal Lobe
Executive functions, movement and planning (primary motor cortex)
-Prefrontal cortex
Prefrontal Cortex
- higher order brain functions
- rational thought, reasoning, decision making, apathy, sense of self
- executive functions (coordination of entire brain, integration of thought processes)
- Broca’s Area
Broca’s Area
If not working, hinders ability to form speech and communicate (tan tan tan tan tan)
Pituitary Gland
Regulates other endocrine glands
Left hemisphere
Fine tuned language skills, speech production/comprehension, facial expressions, motion detection
Right Hemisphere
Course language skills, simple speech, other stuff who knows
Electroencephalogram (EEG)
Electrodes on scalp, measure electric activity waves
Position Emission Tomography (PET)
Visual location of radioactive glucose when brain performs tasks. (Shows which part of brain is associated with what actions)
Magnetic resonance Imaging (MRI)
Pics of brain anatomy with magnetic fields
Functional MRI (FMRI)
Successive MRIs compared to show brain activity, evidenced by 02 in blood flow
Synaptic cleft
Space between neurons
Neuron Types
Sensory, Motor, Interneurons
Neurotransmitters
Chemical messages (outside of neurons)
Emotion, thought, or behavior
Agonist
Mimic/enhance actions of NTs
Antagonists
Inhibit/block NTs
Glutamate
Main excitatory NT
Enhances action potential
Sensory info&learning
*too much over excites brain, associated with schizophrenia
GABA
Main inhibitory NT
Inhibits action potential
Helps sleep, anxiety, intoxication
Acetylcholine
Motor function
Attention, memory, sleep
Norepinephrine
(Adrenaline)
Arousal, alertness, mood, hunger
Serotonin
Emotional state, sleep cycle, impulse control, temperature regulation
*low amounts associated with depression
Dopamine
Reward and motivation, Motor control over voluntary movement, frontal lobe activity
Helps with survival stuff
Endorphins
Pain reduction, rewards
Central Nervous System
The Brain and Spinal Chord
Peripheral Nervous System
Somatic and Autonomic
Somatic
PNS.. conveys info from brain to rest of body, controlling and coordinating VOLUNTARY movements
Autonomic
PNS.. Involuntary movements
- sympathetic
- parasympathetic
Sympathetic
PNS-> Autonomic -> this.
Crisis, fight or flight
Parasympathetic
PNS-> autonomic-> this.
-rest and digestion
Freud
Psychoanalysis, analyzing unconscious/psyche
Behavioralism
Pavlov, Skinner, Watson
All that matters is what you see and how you behave (fuck your psyche, Freud)
Humanism
Maslow
UR gr8!!! Think about where ur goin!! You’re inherently good bby UwU
Cognitivism
U know what…… we probably like,,, use our brains and…,.,. Thi.nk,,,,,
Operational definition
Crystal clear explanation of hypothesis
(Ex: instead of “i think they’ll stand up more” u say “I think they’ll stand up 3 times more than the average of 1 time” or “I think they’ll stand up twice as often than the average”)
Forebrain
Motivation, emotion, complex thought
Cerebral cortex
Controls complex thought process
