in general, what does the frontal lobe involved with?
motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior
which frontal lobe is more involved in controlling language related movement
which frontal lobe is more involved in non-verbal activities?
how might motor look in a pt with a frontal lobe lesion
- loss of fine movements and strength in UE > LE
- complex chains of motor movement also seem to be controled by frontal lobe
facial expressions if you have a frontal lobe lesion?
little spontaneous facial expression
which aphasia is associated w frontal lobe lesion?
L vs R frontal lobe lesion impact on speech
- L: speak fewer words
- R: speak excessively
One of the most common characteristics of frontal lobe damage is difficulty in interpreting feedback from the environment. Give examples
perseveration, risk taking, non-compliance w rules, impaired associative learning (taking cues to help guide behavior)
frontal lobe lesion L vs R impact on personality
- both can significantly impact it, esp if both are involved at once
- L: --> pseudodepression
- R: --> pseudopsychopathic
another generalization of the impact of frontal lobe damage
"The frontal lobe controls motor skills like hand/eye coordination, conscious thought, emotions, and even your personality. As a result of a brain injury, frontal lobe damage may impair your attention span, motivation, judgment, and organizational capacity."
which frontal lobe is incharge of picking up auditory signs like the meaning behind a speaker's tone of voice?
which kinds of emotions does the R vs L frontal lobe deal with?
- R: is more involved with negative emotions
- L: is more involved in positive emotions.
a general view of L frontal lobe damage presentation
Left-sided damage can result in pseudodepression, featuring apathy, indifference, a lack of initiative, but no actual depression. Broca's area in the left frontal lobe is involved with the production of speech, with damage here causing Broca's aphasia. Speech becomes agrammatical and sputtering. A person may be unable to remember the names of things. Words may be substituted for one another. Repetition may not be possible.
a general view of R frontal lobe damage presentation
Right frontal lobe injury can result in pseudopsychopathy, characterized by immature, tactless and unrestrained behavior. According to Dr. P. Shammi of the University of Toronto, right frontal lobe damage can also diminish a person's appreciation for, and response to, humor. A person may fail to smile or laugh when doing so would be appropriate.

- The person ignores his left side.
- He may not wash or properly dress that half of his body.
- He may be unable to make, draw or assemble things.

a lesion where causes Wernicke's aphasia?
L temporal lobe
3 things temporal lobes are involved with
processing visual and auditor info, and forming memories
R temporal lobe lesions -->
- uninhibited speech
- an inability to recognize shapes and non-verbal sounds.
- A familiar tune becomes strange.
- Facial recognition may be lost, making old friends unrecognizable.
