25
Hindbrain component that regulates sleep and carries nerve impulses between higher and lower levels of the Nervous system
Pons
26
Part of the Hindbrain that manages muscular movement and coordination, memory and learning (precise movements, affected by alcohol)
Cerrebellum
27
Part of the brain that contains clusters of sensory and motor nuerons
Midbrain
28
Alerts Higher centres of the brain that messages are coming
Reticular formation (mid brain)
29
Messages are either blocked or allowed by the (such as ignoring noise during sleep and waiting to go to the toilet)
Reticular formation (midbrain)
30
Part of the brain that allows the transmission between hindbrain and forebrain
Midbrain
31
Part of the brain that allows for some monitoring and some transmission, but more importantly, lack of transmission when relevant (ie sleeping)
Midbrain
32
The most evolutionary advanced part of the brain
Forebrain
33
Forebrain contains
Cerebrum Thalmus Hypothalmus
34
Hindbrain contains
Brain stem - Medulla and pons Cerebellum
35
Midbrain
Reticular Formation
36
The major structure of te forebrain that wrap around the brain stem
Cerebrum (two hemishperes)
37
A switchboard that organises inputs from sesory organs and routes them to the appropriate areas
Thalmus
38
Motivation and emotion, sexual behaviour, temperature regulation, eating drinking and aggression are managed by this part of the brain
Hypothalmus (connected to pituitary gland)
39
What part of the brain is connected to the pituitary gland
Hypothalmus
40
The Hypothalmus is connected to which gland
Pituitary
41
The forebrain Contains the
Cerebrum Thalmus Hypothalmus Limbic system (Hippocampus & Amygdala) Cerebral cortex Motor cortex sensory cortex
42
System that coordinates behaviours needed to satisfy motivational and emotional urges (also concerns reward and punishment)
Limbic System (forebrain
43
Limbic System is made up of
Hippocampus & Amygdala (forebrain)
44
Hippocampus & Amygdala are part of the
Limbic System (forbrain)
45
Forms and retrieves memories, memory recording device
Hippocampus (forebrain)
46
Organises motivational and emotional response patterns, fear, disgust, avoidance behaviours
Amygdala (forebrain)
47
Unmyelinated cells that form the outermost layer of the brain
Cerebral Cortex (forebrain)
48
Cerebral Cortex
Unmyelinated cells that form the outermost layer of the brain (forebrain)
49
----% of the cerebral cortex exists in the folds of the wrinkled surface.
76
50
How thick is the cerebral cortex
1/4 inch (63mm)
51
Four lobes of the cerebral cortex
Frontal, Parietal, Temporal, occipital (forebrain)
52
Contains 600+ muscles for voluntary body movement
Motor Cortex (forbrain)
53
Receives input from sensory receptors, heat touch etc
Sensory Cortex (forbrain)
54
The two sense that the most of the brain is allocated to
Touch and Sight
55
Primary motor cortex and Prefrontal cortex and Brocas area are all in the (lobe)
Frontal Lobe (executive function, voluntary movement, higher order attentional decision making)
56
Somatic sensory cortex is in the (lobe)
Parietal Lobe (bodily sensation, memory)
57
Primary Auditory cortex and wrneckes area (lobe)
Temporal Lobe (auditory/memory)
58
Primary visual cortex (lobe)
Occipital lobe (visual processing)
59
Lobe that is responsible for executive function, voluntary movement, higher order attentional decision making
Frontal Lobe
60
Lobe that manages bodily sensation, memory
Parietal Lobe
61
Lobe that manages auditory and memory
Temporal Lobe
62
Lobe that does all our visual processing
Occipital Lobe
63
Not lobes of the brain but very important components, that support the base of the brain
Spinal Cord and brain stem
64
Brocas Area
Production of speech through its connections with the motor cortex regions, comtrol muscle movemnt for speech, expressive aphasia - now disproved that one area does one thing (speech network, not a specific place)
65
Wernickes area
Speech comprehension, Receptive aphasia
66
a disorder that results from damage to portions of the brain that are responsible for language.
Aphasia
67
Located across the brain, anterior, limbic and posterior, often called the silent areas because stimulation does not cause spcific sensory or motor response
The Association Cortex
68
Involved in important mental functions including perception, language and problem solving
The Association Cortex
69
The inability to identify familiar objects
Agnosia
70
Selective inability to recognise familiar human faces
Prosopagnosia
71
Executive function is a large part of the
prefrontal cortex
72
Lateralisation
Left and Right brain theory
73
Brain hemisphere for Verbal abilities speech maths logical abilities , positive emotions arouse it
Left Brain
74
Brain Hemisphere for: Spatial relations, faces, mental imagery, musical and artistic ability more active when feeling negative
Right Brain
75
A neural bridge of myelinated neurons between the two hemispheres allows them to function as a single unit (strip of neurons)
Corpus Callosum
76
The production of new neurons in the nervous system
neuro geneis
77
Immature uncommitted cells that can mature into any type of neuron or glial cell
