Brain Bee Part 6

Front 1

Norepinephrine

Back 1

Catecholamine neurotransmitter. Involved in arousal, sleep regulation, mood and blood pressure

Front 2

Occipital lobe

Back 2

Involved in processing visual information

Front 3

Olfactory bulb

Back 3

Processes sense of smell

Front 4

Orexin neurons

Back 4

Specialised neurons that send excitatory signal to the arousal system. Prevents abnormal transitions into REM sleep

Front 5

Parasympathetic nervous system

Back 5

Branch of autonomic nervous system involved in conservation of body's energy during relaxed states

Front 6

Parietal lobe

Back 6

Involved in sensory processes, attention and language

Front 7

Parkinson's disease

Back 7

Caused by death of dopamine neurons in the midbrain

Front 8

Peptides

Back 8

Short chains of amino acids that can function as neurotransmitters or hormones

Front 9

Peripheral nervous system

Back 9

Consists of nerves that aren't a part of the brain or spinal cord

Front 10

Photoreceptor

Back 10

Nerve ending, cell or group of cells involved in sensing or receiving light

Front 11

Pituitary gland

Back 11

Endocrine organ linked with hypothalamus that secretes hormones

Front 12

Plasticity

Back 12

The ability of the brain to modify neural connections to adapt to challenging environments

Front 13

Pons

Back 13

Part of hindbrain that controls respiration and regulates heart rhythm

Front 14

Positron emission tomography (PET)

Back 14

Detects radioactivity emitted by positrons undergo radioactivity in the brain, to measure brain function

Front 15

Psychosis

Back 15

Severe symptom of psychiatric disorders characterised by an inability to perceive reality

Front 16

Rapid eye movement (REM) sleep

Back 16

Part of sleep cycle where dreaming occurs and also when muscles become paralysed

Front 17

Reflexes

Back 17

Fixed, automatic muscle responses to particular stimuli

Front 18

Retina

Back 18

Sensory tissue at the back of the eye that contains receptor cells that detect light

Front 19

Reuptake

Back 19

Process where released neurotransmitters are absorbed for later reuse

Front 20

Rod

Back 20

Sensory neuron in retina, specialised for nighttime vision

Front 21

Schizophrenia

Back 21

Chronic disorder characterised by psychosis

Front 22

Second messengers

Back 22

Substances that trigger communications after the actions of neurotransmitters have been completed
