Page 158 - are measured before they enter consciousness, we have proposed the word " schema." By means of perpetual alterations in position we are always building up a model of ourselves, which constantly changes. Every new posture or movement is
Page 157 - strongly. But in both cases the image, whether it be visual or motor, is not the fundamental standard against which all postural changes are measured. Every recognizable change enters into consciousness already charged with its relation to something that has
Page 351 - of the finer voluntary movements; but the activity of the lower centres, released from control, was evident in the spastic rigidity of the paralysed parts. In the same way, removal of the control, normally exercised by the cortex over the activity of the optic thalamus, leads to the remarkable condition known as thalamic over-reaction;
Page 353 - The charm of neurology, above all other branches of practical medicine, lies in the way it forces us into daily contact with principles. A knowledge of the structure and functions of the nervous system is necessary to explain the simplest phenomena of disease, and this can be only attained by thinking scientifically.
Page 227 - Case 15.—Wounded August 20, 1916, over the vertex in the parietal region. The wound extended slightly more to the right than to the left of the middle line. This case is remarkable because the three aspects of cortical sensibility were dissociated
Page 158 - fresh group of sensations evoked by altered posture into relation with it. Immediate postural recognition occurs as soon as this relation is complete.
Page 158 - Recognition of posture and movement is obviously a conscious process. But the activities on which depend the existence and normal character of the schemata lie for ever outside consciousness ; they are physiological processes with no direct psychical equivalent. The conduct and

In many cases the higher function could not be exercised without the existence of those lower powers which it dominates and controls. Postural reflexes, strictly adapted to conditions of space and time, could not occur without the

In many cases the higher function could not be exercised, without the existence of these lower powers which it dominates and controls. When, however, the higher mechanism is thrown out of action the functions of the lower
