Deeper
brain regions which we may vaguely describe as subconscious—for instance we are
not constantly aware of the proprioceptive information that the cerebellum uses
to maintain balance Several of the subtests can reveal activity associated with
these sensory modalities such as being able to hear a question or see a picture
Two subtests assess specific functions of these cortical areas The first is
praxis a practical exercise in which the patient performs a task completely on
the basis of verbal description without any demonstration from the examiner For
example the patient can be told to take their left hand and place it palm down
on their left thigh then flip it over so the palm is facing up and then repeat
this four times The examiner describes the activity without any movements on
their part to suggest how the movements are to be performed The patient needs
to understand the instructions transform them into movements and use sensory
feedback both visual and proprioceptive to perform the Inteligen Side
Effects correctly The
second subtest for sensory perception is gnosis which involves two tasks The
first task known as stereo gnosis involves the naming of objects strictly on
the basis of the somatosensory information that comes from manipulating them The
patient keeps their eyes closed and is given a common object such as a coin that
they have to identify The patient should be able to indicate the particular
type of coin such as a dime versus a penny or a nickel versus a quarter on the
basis of the sensory cues involved For example the size thickness or weight of
the coin may be an indication or to differentiate the pairs of coins suggested
here the smooth or corrugated edge of the coin will correspond to the
particular denomination The second task graphesthesia is to recognize numbers
or letters written on the palm of the hand with a dull pointer such as a pen
cap Praxis and gnosis are related to the conscious perception and cortical
processing of sensory information Being able to transform verbal commands into
a sequence of motor responses or to manipulate and recognize a common object
and associate it with a name for that object Both subtests have language
components because language function is integral to these functions.
