Brain Parts
The wrinkly part of the brain in which most of what we consider "thinking" takes place
cerebrum
Nerve cells receive impulses from sensory receptors and send them to the central nervous system and brain.
sensory neurons
Lies directly behind the forehead. When you plan a schedule, imagine the future, or use reasoned arguments, these two lobes do much of the work. Doesn't fully develop until 25.
frontal lobe
these are the long branchlike structure that extend from the soma and receive signals from other neurons
dendrites
This part of the brain, still developing in teens, helps with planning and decision-making.
Pre-frontal cortex
This part of the brain deals with body systems and involuntary functions
the brain stem
The nerve cells that receive information from the brain and connect to muscles to cause movement.
Motor neurons
Whether you appreciate symphonies or rock music, your brain responds through the activity of these lobes, which is responsible for receiving information from the ears.
temporal lobe
this fatty substance allows signals to travel along the axon faster and with more efficiency
myelin
This term describes the brain’s ability to change and adapt through learning and experience.
Plasticity/ Malleability
in the hindbrain, this part of the brain is responsible for movement and coordination
allows sensory and motor neurons to communicate with each other.
relay or interneurons
This lobe on the top of your brain processes touch, pain, and pressure, and that plays a key role in spatial awareness, memory, and navigation.
Parietal Lobe
This is the long tail of the neuron along which a signal travels
axon
This chemical messenger linked to reward motivates teens to seek exciting experiences.
Dopamine
This part of the brain is where memories are stored
The hippocampus
The part of the nervous system that contains the brain and spinal cord
The Central Nervous System
These lobes, called the_____, process images from the eyes and link that information with images stored in memory.
occipital
the place where a signal passes from the neuron to another cell.
synapse
This process removes unused neural connections, making the brain more efficient.
What is pruning?
Part of the midbrain, it is a large, egg-shaped structure located in the center of the brain. It acts as a relay station for sensory information from the body to the cerebral cortex.
thalamus
The Part of the Nervous System that contains all the neurons that send information from the rest of the body to the brain and spinal cord
Peripheral nervous system
This lobe works closely with the limbic system to connect sounds with memories and emotions.
Temporal Lobe
The cell body of a neuron is called the _____. Its job is to_____
soma, keep the cell alive
Why we remember adolescence so vividly — the emotional and reward systems are highly active.
Heightened limbic activity (or strong emotional encoding during adolescence)
An almond-shaped structure located in the temporal lobe of the brain. It plays a crucial role in processing emotions, particularly fear, anxiety, and aggression.
Amygdala
The peripheral nervous system is broken into what two groups?
Sensory and motor
Damage to this lobe can affect a person’s ability to understand language, plan actions, or control impulses.
Frontal Lobe
These small branches at the end of the axon send information to other neurons.
Axon Terminals
This part of the brain, active in reward processing, makes peer approval feel especially powerful to teens.
ventral striatum
