It's Basic!
How much does the brain weigh?
3-ish pounds
What is the primary function of the frontal lobe?
Controls organization and decision-making.
What does the thalamus do?
It directs sensory information to other parts of the brain.
What is the primary role of the limbic system?
Generates emotions and processes emotional memories
Which cere- coordinates balance and coordination?
Cerebellum
What fruit is comparable in size to the human brain?
Grapefruit
Which lobe is responsible for processing visual cues?
Occipital lobe
What is the role of the hippocampus in learning?
It brings information together for learning and converts it from working memory into long-term storage.
Located between the cerebrum and the brain stem, the limbic system combines both __ and __.
Emotion and reason interplay here.
The cerebrum helps improve performance and timing because it holds onto repetitive, automatic movements through __.
Muscle memory.
The brain is divided into 2 parts, commonly known as left and right __
Hemispheres
What are the key functions of the temporal lobe?
Oversees memory, hearing, understanding, and language.
What does the brain stem regulate?
It monitors and controls heartbeat, respiration, body temperature, and digestion.
What functions do amygdala have regarding memory?
It encodes memories with emotions, usually fear, before they go to long-term storage.
Which cere- is a support structure for cognitive processing, allowing the brain to attend to mental activities without much attention to detail?
-bellum
What bundle of nerves connects the two hemispheres?
Corpus callosum
What does the parietal lobe integrate?
Sensory information (temperature, touch, pain) from various parts of the body.
How does the hypothalamus maintain homeostasis (process of ideal self-regulation)?
It controls body temperature, sleep, food, and liquid intake through hormone balance.
What is the amygdala's main job?
SURVIVAL! It scans the environment for threats to inform the body to attack, escape, eat, or mate.
The cortex covers the hemispheres in the cerebrum to assist in which processes?
Thinking, memory, speech, and muscular movement
What is unusual about the nerves in the right and left hemispheres of the brain?
Controlled by the other hemisphere. Nerves from the left side of the body cross over into the right hemisphere, and vice versa.
What is something unique about the development of the frontal lobe?
This area controls decision-making and rational decision-making, and is the slowest to develop.
What part of the brain is known as the "reptilian" brain?
Brain stem.
How does the limbic system impact behavior?
It influences emotional responses and social behavior.
Which cere- is the largest area, representing nearly 80% of the brain by weight?
Cerebrum
