Abstract
Abstract The present subject matter is directed to a method for treating a conscious. The method includes selecting a conscious patient having impaired cognitive function and applying electrical stimulation to at least a portion of the patient's intralaminar nuclei under conditions effective to relieve the patient's impaired cognitive function. A method for improving coordination of function across a patient's cortical regions is also described. The method includes applying electrical stimulation to two or more subdivisions of the patient's intralaminar nuclei. The two or more subdivisions of the patient's intralaminar nuclei modulate separate cortical regions. Using the methods of the present invention, patients suffering from impaired cognitive function can have at least a portion of the function restored, thus improving their quality of life and reducing societal costs.

Claim 7
Dependent Claim
16 words
A method according to claim 1, wherein the electrical stimulation is modulated externally of the patient.
Claim 8
Dependent Claim
14 words
A method according to claim 1, wherein the cognitive function impairment exhibits spontaneous fluctuation.
Claim 9
Dependent Claim
17 words
A method according to claim 1, wherein the electrical stimulation is directed to the patient's paralamellar regions.
Claim 10
Dependent Claim
24 words
A method according to claim 1, wherein the electrical stimulation is applied only to the at least a portion of the patient's intralaminar nuclei.

Dependent Claim
21 words
A method according to claim 1, wherein the impaired cognitive function involves a deficit of attention, intention, working memory, or awareness.
Claim 12
Dependent Claim
42 words
A method according to claim 1, wherein the patient's impaired cognitive function results from a brain injury produced by stroke, blunt head trauma, missile penetration, toxicological agents, anoxia, ischemia, nutritional deficiencies, developmental diseases, degenerative diseases, infectious diseases, neoplastic diseases, or complications thereof.
Claim 13
Dependent Claim
47 words
A method according to claim 1, wherein said method involves treating a specific cognitive function impairment and further comprises: identifying a subdivision of the patient's intralaminar nuclei which modulates the specific cognitive function, and wherein said applying electrical stimulation is directed to at least the selected subdivision.
Claim 14
Dependent Claim
18 words
