PHYS 2 Voluntary Motion Flashcards
cortical areas associated with production of voluntary movement?
3 main plus 2 more
where are they located?
roles? broad not specific just in general single/multiple/segregated/cooperative
each of these areas has multiple roles and in some cases overlapping roles
reaching vs grasping for an object when it comes to motion?
what allows us to complete motor acts based on visual input? this pathway comes from where? then goes where?
voluntary motion: reaching
from visual cortex information is relayed to where? specifically? (4)
end result? what creates what?
in order to reach effectively you need info about the object’s location in relation to your body
Voluntary motion: reaching
from the VIP information is sent to what? within?
end result: this area creates what? when do neurons here fire more frequently?
voluntary motion: reaching
second pathway at work. comes from what cortex? recieves visual info about what?
this input is sent to where?
end result: this area constructs what?
visual cues related to grasping are differnt how? need to pay attention to what?
visual cues related to grasping are quite different and very dependent on exactly what you intend to do
we need to pay attention to the features of the item we are interested in picking up
voluntary motion: grasping
what area are we interested in? contains neurons that respond to what? (3) for each type of dominance?
where is this area located?
voluntary motion: grasping
AIP/PFG relay their info to where?
neurons where fire with what stim? not _____?
Neurons in F5 fire with GOAL of action not the motor act itself (grasping)
which means that the same F5 neurons will be active when?
in contrast when would it be different?
voluntary motion premotor cortex
summary
receives what info? particularly from?
Dorsal does what?
identifies the ____ of the motion and decides what?
voluntary motion: supplementary motor cortex
two divisions?
s- function?
p- function?
voluntary motion: supplementary motor cortex
3 roles?
- organize?
- acquire?
- particularly what?
somewhat of a summary of voluntary motion up to before motor neurons get activated.
premotor does what? then pre-SMA?
primary motor cortex pretty much
voluntary motion: primary motor cortex
location? controls what?
what areas have high representation?
arranged in?
voluntary motion: primary motor cortex
stimulation of any give column produces what?
area that controls fine motion stimulation may produce?
area that controls more general motion stimulation may produce?
voluntary motion: primary motor cortex
broken down into how many layers?
layer 4 receives what input?
voluntary motion: primary motor cortex
layer 5 becomes what?
voluntary motion: primary motor cortex
how many sets of neurons in each column?
what is each do?
voluntary motion: primary motor cortex
neighboring columns control what? not?
voluntary motion: primary motor cortex
seem to be two types of columns
1.
2.
what are they?
voluntary motion: primary motor cortex
each individual motion required to pick up candy coded for by?
cortex plans motion without additional parts youll not be able to properly grab (probably crush candy and miss mouth)
Voluntary motion: cerebellum
role of the cerebellum? (4)
Voluntary motion: cerebellum
in physiology how is the cerebellum divided?
not asking for the specific divisions
Voluntary motion: cerebellum
more medial division is called?
two regions of this?
what is each in control of?
voluntary motion: cerebellum
lateral part? name?
functions?
what is sequence?
Voluntary motion: cerebellum
third portion
named?
function?
timing?
Voluntary motion: cerebellum
outputs from cerebellum are via?
(3)
there are 2 subsets of one of these
Voluntary motion: cerebellum
central region of spinocerebellum (location) function?
inputs? (3)
outputs? (3)
Voluntary motion: cerebellum
more lateral region of spinocerebellum
function?
inputs? (2)
outputs? (2)
Voluntary motion: cerebellum
cerebrocerebellum
function?
inputs (1)
outputs (2)
Voluntary motion: cerebellum
vestibulocerebullum
function? particularly in?
input? (1)
output? (2)
