Sleep spindles occur at this stage, these are brief bursts of higher frequency brain waves that appear on EEG readings.
What is stage 2 sleep?
100
During adolescence the body moves forward by 2 hours.
What is delayed sleep onset?
(body clock shift due to delayed release of sleep inducing hormone melatonin)
100
Receptors detect neurotransmitters and transmit this message to the cell body (soma). When new memories are formed, the number increases.
What is a dendrite?
100
Found in each hemisphere and regulates emotional reactions such as fear and anger.
What is the amygdala?
100
This information will pass from sensory to STM to LTM if we rehearse it in ways that give it meaning that allows us to link material to exisiting memories in LTM.
What is Atkinson-Schiffrin model ?
200
Lower electrical activity than NREM-due to REM paralysis.
What is EMG?
200
The effects are temporary and tend to only last until the individual is able to sleep. Person falls asleep quicker and longer.
What is total sleep deprivation?
200
Involvced in learning, attention, sleeping, dreaming and motor control, it is found to be at an abnormally low level in the brains of people suffering from Alzheimer's disease.
What is the neurotransmitter acetylcholine?
200
Part of the brain that has a vital role in controlling many bodily functions including the release of hormones.
What is the hypothalamus?
200
Active memory system that has different stores for different types of information. Latest model was given an additional component.
What is Baddeley & Hitch's model of Working Memory (2000)?
300
Restores our mental functioning (helps get "our mind right") but also assists with learning and memory i.e consolidation of information processed during the day by strengthening neural circuits.
What is REM sleep?
300
It would detect, amplify and record a high level of electrical activity during REM.
What is an EOG reading?
300
The long lasting strengthening of synaptic connections of neurons, resulting in the enhanced or more effective functioning of the neurons whenever activiated.
What is long-term potentiation (LTP)?
300
Represents the body parts in terms of relative size of the area each body part occupies along the primary somatosensory cortex.
What is the homunculus?
300
Diagnosis and classification of mental disorders based on recognised symptoms. Includes detailed description of disorder. Provides detailed list of symptoms for each disorder, no information of prevalance of disorder.
What is the ICD-10?
400
Humans sleep at night due to our visual limitations when there is an absence of light, thus reducing our risk of harm.
What is the survival theory of sleep?
400
Experiencing up to double the usual amount of REM- ie 40% of their sleep is REM (rather than the usual 20%).
What is REM rebound?
400
Plays a crucial role in the structural changes that occur, particularly in the growth and strengthening of synaptic connections between neurons within a memory circuit.
What is the neurotransmitter glutamate?
400
Damage to this structure does not seem to seriously affect storage or retrieval of procedural memory, but formation and retrieval of declarative memories are affected. Is not involved in short term storage.
What is the hippocampus?
400
A major limitation is it is difficult to test through experimental research because of subjective nature, variability and complexity of individual responses to experiences.
What is the Transactional Model of Stress & Coping (1984)?
500
It would detect a normal level of electrical conductivity of the skin.
What is the GSR reading during normal waking consciousness?
500
A loss of awareness that lasts for a few seconds up to 2 minutes, that is a result of sleep deprivation.
What is microsleep?
500
They communicate with each other, muscles and glands. Vary in shape and size depending on where they are located and their specific function.
What is a neuron?
500
There seems to be an ideal level for working memory to function properly. Roles played in attention, inititation of voluntary movement, experience of pleasure and reward based learning.
What is dopamine?
500
An accident with a tamping iron made history's most famous brain-injury survivor. Severe frontal lobe damage affected several aspects of his personality.
