The Outer Shell (Cerebrum/Lobes)
This lobe, located at the very front of the brain, is responsible for decision-making and personality.
What is the Frontal Lobe?
In the teenage brain, this almond-shaped structure is often hyper-reactive, leading to intense emotional responses.
What is the Amygdala?
Meaning "tough mother" in Latin, this is the outermost, thickest layer of the meninges.
What is the Dura Mater?
This lowest part of the brainstem controls involuntary "must-haves" like breathing and heartbeat.
What is the Medulla Oblongata?
This stage of sleep is characterized by high brain activity and vivid dreaming.
What is REM sleep?
If you are looking at a sunset, this rear-most lobe is busy processing the visual information.
What is the Occipital Lobe?
This "CEO" of the brain is the last part to fully mature (around age 25), explaining why teens may struggle with impulse control.
What is the Prefrontal Cortex?
This clear fluid cushions the brain and circulates nutrients while removing waste.
What is Cerebrospinal Fluid or CSF?
This bridge-like structure connects the cerebrum to the cerebellum.
What is the Pons?
A mild traumatic brain injury (TBI) often caused by a bump or blow to the head that shakes the brain inside the skull.
What is a Concussion?
What is the Longitudinal Fissure?
This "valley" or groove separates the left and right hemispheres of the cerebrum.
This limbic structure is essential for forming new long-term memories; it's named after the Greek word for "seahorse."
What is the Hippocampus?
These are the four hollow "chambers" inside the brain where CSF is produced.
What are the Ventricles?
This diffuse network of neurons acts as the brain's "alarm clock," regulating alertness and arousal.
What is the Reticular Formation?
This hormone, produced by the pineal gland, signals to the brain that it is time to sleep.
What is Melatonin?
What is the Temporal Lobe?
Located near the temples, this lobe is the primary center for hearing and language comprehension.
The "reward chemical" that floods the teenage brain during risky or exciting activities.
What is Dopamine?
The middle, web-like layer of the meninges.
What is the Arachnoid Mater?
Damage to the Reticular Formation can result in this state of prolonged unconsciousness.
What is a Coma?
An imbalance of this neurotransmitter in the basal ganglia is the primary cause of Parkinson’s Disease.
What is Dopamine?
What is the Somatosensory Cortex?
This specific strip of the parietal lobe allows you to feel a mosquito land on your arm.
This structure acts as a relay station, sitting atop the brainstem and directing sensory info to the correct part of the cortex.
What is the Thalamus?
Inflammation of the protective membranes surrounding the brain, often caused by a viral or bacterial infection.
What is Meningitis?
This tiny region controls the "Four F's" (Fighting, Fleeing, Feeding, and... Mating) and regulates body temperature.
What is the Hypothalamus?
A condition where the brain produces too much CSF, or cannot drain it, leading to increased intracranial pressure.
What is Hydrocephalus?
