Abstract
Abstract A method and apparatus for enhancing a person's cerebral functions by providing a selective increase in the cerebral temperature while leaving the temperature of the rest of the body as is. The method and apparatus elevate the exterior skull temperature to a selected value within the range between 38° and 50° Celsius and change the temperature within a limited rate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
Cortical temperature -- elevating apparatus for imposing a selected elevated body-differential cortical temperature to a person, said apparatus comprising A. controllable thermal means for the localized heatinhg of the head of a person, B. sensor means for sensing the temperature of the person's head, and C. control means connected with said sensor means to receive a temperature-responsive signal and controlling in response thereto said thermal means to apply a temperature selected from the range between 38° and 50° C to the person's head, with a maximum rate of temperature increase below 1.0° C per minute.
Claim 2
Dependent Claim
95 words
Cortical temperature -- elevating apparatus for imposing a selected elevated body-differential cortical temperature to a person, said apparatus comprising A. controllable thermal means for the localized heatinhg of the head of a person, B. sensor means for sensing the temperature of the person's head, and C. control means connected with said sensor means to receive a temperature-responsive signal and controlling in response thereto said thermal means to apply a temperature selected from the range between 38° and 50° C to the person's head, with a maximum rate of temperature increase below 1.0° C per minute.
Claim 3
Dependent Claim
22 words
Apparatus according to claim 1 incuding a head garment mounting said thermal means for relatively high heat transfer with a wearer's head.
Claim 4
Dependent Claim
29 words
Apparatus according to claim 2 in which said sensor means includes a temperature sensor mounted with said garment for disposition in relatively close thermal contact with the wearer's head.
Claim 5
Dependent Claim
16 words
Apparatus according to claim 2 in which said sensor means includes a tympanic membrane temperature sensor.
Claim 6
Dependent Claim
46 words
Apparatus according to claim 1 further characterized in that said control means includes means for controlling said thermal means to regulate the rate of temperature decrease from said selected elevated temperature to the person's present normal level at a maximum rate below 0.5° C per minute.
Claim 7
Dependent Claim
26 words
Apparatus according to claim 1 further characterized in that said control unit includes means for limiting the rate of temperature increase to 0.8° C per minute.
Claim 8
Dependent Claim
32 words
Apparatus according to claim 6 further characterized in that said control unit includes means for limiting the rate of temperature decrease from an elevated level to normal, to 0.4° C per minute.
Claim 9
Independent Claim
83 words
A method for enhancing human cerebral functioning comprising the steps of A. selectively elevating the cortical temperature by imposing a selected elevated body-differential temperature to the person's head, B. monitoring the head temperature during at least the interval of said temperature-elevation, and C. controlling the elevation of the head temperature in response to said monitoring to a temperature selected from the range between 38° C and 50° C, and controlling the rate of temperature increase to be less than 0.8° C per minute.
Claim 10
Independent Claim
83 words
A method for enhancing human cerebral functioning comprising the steps of A. selectively elevating the cortical temperature by imposing a selected elevated body-differential temperature to the person's head, B. monitoring the head temperature during at least the interval of said temperature-elevation, and C. controlling the elevation of the head temperature in response to said monitoring to a temperature selected from the range between 38° C and 50° C, and controlling the rate of temperature increase to be less than 0.8° C per minute.
Claim 11
Dependent Claim
42 words
A method as defined in claim 8 in which said controlling step further includes the step of controlling the rate of temperature decrease from said selected temperature to the person's present normal level to a maximum rate of 0.4° C per minute.
