Intracranial 3 major subdivisions
Forebrain
Cerebellum
Brain stem
Intracranial forebrain subdivision
Cerebrum
Diencephalon
Intracranial brainstem subdivision
Mid brain (mesencephalon)
Pons (ventral metenceohalon)
Medulla (myelencephalon)

Localize the seizure!
Forebrain
4 hallmarks of forebrain lesion localization
Seizures
Normal gate
Blind with normal PLR
Behavior changes
Deficits associated with intracranial cerebrum/forebrain lesion
Seizure Normal gate Blind w/ normal PLR Behavior changes Circling (towards the lesion) Head pressing Menace deficit on contralareral side Hemi neglect
Deficits associated with intracranial diencephalon/forebrain lesion
Similar to cerebrum lesions
AND
Endocrine dysfunction - depending on hypothalamus/purity the involvement (PU/PD thalamic pain sydrome ect)
Decreased/absent menace (depending on involvement of optic N/lateral geniculate nucleus (LGN))
Stupor/coma - depending on ascending reticular activating system ARAS (mostly in brainstem but some communication to diencephalon)
