Brain parts vocab
| Term | Definition |
|---|---|
| Hindbrain | Medulla, pons, reticular formation, cerebellum |
| Midbrain | Basal ganglia - substantia nigra |
| Forebrain | Thalamus, hypothalamus, amygdala, hippocampus, cerebral cortex, pituitary gland, septum, cingulate gyrus, corpus callosum |
| Medulla | Controls automatic functions |
| Pons | (Bridge) Connects cerebellum/ medulla to the rest of brain, controls facial expressions/ breathing |
| Reticular Formation | Reward center (dopamine), regulates arousal, sleep/wake, pain reception, controls consciousness |
| Cerebellum | Controls voluntary coordination (fine), aids in nonverbal learning/ memory |
| Basal Ganglia (Substantia Nigra) | Makes movements smooth, helps with the ability to stop moving, plan sequences of behavior Produces dopamine that aids in smooth movement |
| Thalamus | "Relay station", sends sensory information to other parts of brain |
| Hypothalamus | (Below/next to thalamus) Controls the 5 F's - Fight/flight, fun, food, Fahrenheit, fornication (drives related to survival) |
| Amygdala | (At the end of each hippocampal arm) Emotional processing - fear, aggression, anger |
| Hippocampus | (Wrapped around thalamus) Converts short term memory to long term memory for recall |
| Cerebral Cortex | Thought, reasoning, decision-making Somatosensory cortex, Broca's area, Wernicke's area, angular gyrus, primary motor cortex, olfactory bulbs 4 lobes - Frontal (Motor cortex, Somatosensory cortex), Parietal, Occipital, Temporal |
| Pituitary Gland | "Master gland" of endocrine system Regulates hormones (growth, oxytocin...) - release/ production |
| Septum | Regulates aggression/ rageful behavior |
| Cingulate Gyrus | Associates memories to smell/pain Contributes to focus |
| Corpus Callosum | Connects hemisphere of cerebral cortex |
| 4 main lobes | Frontal, Occipital, temporal, parietal |
| Frontal Lobe | Executive decision maker (interprets info from other areas and decides what to do with it) Planning/ decision making/ reasoning Memory/ personality/ emotions/ social control |
| Occipital Lobe | Process visual info Where we see |
| Temporal Lobe | Process auditory info Process taste/smell Recognize faces (LEFT ONLY - essential for understanding/ speaking language) |
| Parietal Lobe | Perceive stimuli related to touch/ pressure/ temperature/ pain Process visual info |
| Motor Cortex | Where movement messages occur Sends messages to other parts of body |
| Somatosensory Cortex | Process touch sensitivity Most sensitive touch area (more area dedicated sense) - ex. fingertips vs back |
| Broca's Area | (In left Frontal lobe next to motor cortex - area that controls facial movement) Allows for speech |
| Wernicke's Area | (Left temporal lobe only) Allows for language understanding |
| Angular Gyrus | (In left parietal lobe) Taking in visual info, converting into auditory code for understanding (hearing voice in head while reading) |
