We used gratings and shapes defined by relative motion to investigate selectivity for static kinetic boundaries in macaque V4 neurons. Kinetic gratings were generated by random pixels moving in opposite directions in the neighboring bars, either parallel to the orientation of the boundary (parallel kinetic grating) or perpendicular to the boundary (orthogonal kinetic grating). Neurons were also...

This study examined neuronal activity in the prefrontal cortex (PF) involved in the process of motor selection in accordance with two behavioral rules. We trained two monkeys to select a target based on the integration of memorized and current sensory information. Initially, a sample cue (triangle or circle) appeared at one of three locations (top, left, or right) for 1 s. After a 3-s delay, on...
shape-selective methylation of naphthalene (naph) over sapo-11 zeolite was carried out in a fixed-bed flow reactor under atmospheric pressure. some zeolites, such as h-beta (hβ), husy and zsm-5 were also evaluated for comparison with sapo-11 zeolite.the results showed that sapo-11 exhibited higher stability, higher selectivity of 2,6-dimethylnaphthalene (2,6-dmn), and higher 2,6-/2,7-dmn ratio...
A single case study of a patient with 'visual form agnosia' is presented. A severe visual recognition deficit was accompanied by impairments in discriminating shape, reflectance, and orientation, although visual acuity and colour vision, along with tactile recognition and intelligence, were largely preserved. Neuropsychological and behavioural investigations have indicated that the patient is a...
