The termination of geniculocortical fibres within the different subdivisions of lamina IV in area 17 of the visual cortex of the monkey has been studied quantitatively with the electron microscope. In lamina IVC alpha the axon terminals of fibres coming from the magnocellular layers of the lateral geniculate nucleus (LGN) make significantly more synapses(More)
A study has been made of the number and distribution of the Meynert cells in area 17 of the visual cortex in the macaque monkey. There are between 30 000 and 40 000 Meynert cells in one hemisphere and these are randomly distributed with an average uniform area density of about 25 cells per square millimetre. The area density of Meynert cells is similar in(More)
Patients with spinal cord injury or multiple sclerosis were surveyed for the presence of extreme foot deformities and spasticity. Pes cavus and claw toes were found in eight of 80 spastic spinal cord injury and two of 20 multiple sclerosis patients. Pes cavus and claw toes were not found in 29 flaccid spinal cord injury patients. Pes cavus and claw toes(More)
Flexor reflexes were compared with phasic stretch reflexes in 12 acute spinal cord injury patients with upper motor neuron lesions. Initial flexor reflex activity appeared later than initial stretch reflex activity in the majority of cases whereas maximal flexor reflexes developed at about the same time as maximal stretch reflexes. A quantitative method for(More)
