Major Brain Landmarks
What is the cerebrum?
The cerebrum is the largest part of the human brain
Amphioxus
Where does the visual cortex send signals to?
What are spinal tracts?
What happens when a signal arrives at a brain region?
They engage local neural circuits.
What are the thalamus, hypothalamus, and pituitary gland a part of?
The thalamus, hypothalamus, and pituitary gland are part of the forebrain.
In early vertebrates, how many distinct bulges were the brain part of the nerve cord, and what were they?
Three; The forebrain, midbrain, and hindbrain.
What does EEG stand for, and what are they more commonly known as? (Correct pronunciation or no points)
Electroencephalograph;brain waves
What do networks that loop the hippocampus into sensory cortex pathways do?
They help your brain analyze whether environmental signals are familiar or part of a new situation.
What do neuroscientists think each column in the cortex does?
They believe that each column of neurons is dedicated to one very specific processing task.
Where are the occipital lobes located?
Over time as the needs for the brain changed, different parts of the brain _________
Expanded
Are beta or alpha waves generally faster?
Beta waves are faster most of the time.
What are reflex loops
In the cerebral cortex, circuits are arranged in _______, as each neuron forms connections with cells int eh layers ______ and _____.
Columns;above;below
The cerebral cortex, the outermost layer of the brain has wrinkles. The more wrinkles it has, the more space it has for neurons, meaning more brain power.
Alpha and beta waves.
What do related networks linking the hippocampus to the thalamus allow?
They allow your memory to influence conscious behavior and unconscious physiological responses.
What are neural circuits?
Interconnected neurons that turn entering signals into output patterns that can be sent to other parts of the brain.
Where are the temporal lobes located AND, what functions do they carry out?
The temporal lobes are located on the sides of the brain, below the eyes. They process some visual and auditory information.
What was one of the regions in early vertebrates which expanded, allowing more complex visual signals to be processed?
Light-sensing regions
EXPLAIN: What happens in your brain when you watch a movie?
*IF YOU DO NOT SAY IT IN YOUR OWN WORDS, THE OTHER TEAM WINS THE POINTS*
When you watch a movie, your photoreceptors create electrical signals from wavelengths of light, sent to the optic nerve. They go along the optic tractor to the thalamus, where they find out the shape, color, and movement of the screen. They pass signals to the primary visual cortex in the occipital lobe. Neurons make it three dimensional(Answers may vary)
Where do the signals sent by spinal tracts go?When they travel up, what happens? What happens when they move down?
On the cerebral cortex, how are neurons organized?
They are organized into a stack of distinct layers that span the thickness of the cortex.
