Brain Matters
This hormone regulates sleep-wake cycles.
What is melatonin?
These cells detect colors
What are cones?
Sound waves are converted to neural signals in this structure.
What is the cochlea?
Taste receptors are located in these structures.
What are taste buds?
Vesicles store these chemicals before release into the synapse.
What are neurotransmitters?
This stage of sleep is associated with vivid dreaming.
What is REM sleep?
The ability to detect a difference between stimuli is this.
What is a difference threshold?
These cells are responsible for night vision.
What are rods?
Skin receptors detect pressure, temperature, and this.
What is pain?
This process allows neurotransmitters to cross the synapse.
What is diffusion?
The body’s internal biological clock is this
What is circadian rhythm?
This process allows neurotransmitters to cross the synapse.
What is diffusion?
This sense detects airborne chemicals.
What is olfaction?
This sense helps maintain balance and spatial orientation.
What is vestibular sense?
This type of signal makes a neuron less likely to fire.
What is inhibitory signal?
Damage to this area affects facial recognition.
What is temporal lobe?
The process of converting stimuli into neural signals is this.
What is transduction?
The blind spot occurs where this structure exits the eye.
What is the optic nerve?
Awareness of body position is this sense.
What is kinesthesia?
The brain’s interpretation of sensory input is this.
What is perception?
This technique measures brain activity using electrical signals.
What is an EEG?
The minimum stimulation needed to detect a stimulus is this.
What is absolute threshold?
The tiny hair cells in the ear are responsible for this process.
This theory explains how the brain can block pain signals.
What is gate-control theory?
Organizing and interpreting sensory information is known as this.
What is perception?
