Previous research had suggested a relationship between averaged cortical evoked response (AER) characteristics and the perception of stimulus intensity. In this study a systematic relationship was hypothesized between AER characteristics and performance on traditional sensory threshold procedures. Averaged evoked responses to light flashes and performances on a battery of psychophysical tasks were measured in 20 normal volunteers. Ss with one AER pattern were sensitive to low-intensity stimulation; Ss with another AER pattern exhibited the opposite response tendency. These findings were interpreted in terms of a theoretical construct regarding a stimulus-intensity control mechanism in the central nervous system.

Intensity Control

The perceived intensity of a stimulus may be magnified during depression. Stimulus intensity control can be studied by means of cortical evoked potentials. In a study of 33 depressives, cortical evoked potentials were greater during depression than on recovery. The effect of doxepin on the amplitudes of evoked potentials of depressives was compared with that of amitriptyline. Doxepin reduced amplitudes. Amitriptyline had a similar, but non-significant effect.

Rod And Frame

There has been only one study with normals which examines relationships among Silverman's three dimensions of attention (cf. Silverman & King, 1970). The present study examined the relationship between scores of normal females on tasks that correlate with factors interpreted as field-articulation control and stimulus-intensity control. No significant linear or curvilinear relationships were obtained from Ss' scores on the rod-and-frame test and the kinesthetic figural aftereffects' test. These results support the belief that field-articulation control and stimulus-intensity control are independent cognitive controls in normals.

Biphasic Responses

ABSTRACT:Cutaneous reflexes in the upper limb were elicited by stimulating digital nerves and recorded by averaging rectified EMG from proximal and distal upper limb muscles during voluntary contraction. Distal muscles often showed a triphasic response: an inhibition with onset about 50 ms (Il) followed by a facilitation with onset about 60 ms (E2) followed by another inhibition with onset about 80 ms (12). Proximal muscles generally showed biphasic responses beginning with facilitation or inhibition with onset at about 40 ms. Normal ranges for the amplitude of these components were established from recordings on 22 arms of 11 healthy subjects. An attempt was made to determine the alterent fibers responsible for the various components by varying the stimulus intensity, by causing ischemic block of larger fibers and by estimating the afferent conduction velocities. The central pathways mediating these reflexes were examined by estimating central delays and by studying patients with focal lesions
