Spatial attention shifts receptive fields in monkey extrastriate visual cortex toward the focus of attention (S. Ben Hamed, J. R. Duhamel, F. Bremmer, & W. Graf, 2002; C. E. Connor, J. L. Gallant, D. C. Preddie, & D. C. Van Essen, 1996; C. E. Connor, D. C. Preddie, J. L. Gallant, & D. C. Van Essen, 1997; T. Womelsdorf, K. Anton-Erxleben, F. Pieper, & S. Treue, 2006). This distortion in the reti...

Although there has been widespread interest in the relationship of diet to atherosclerosis and its complications, much less attention has been paid to the effect of diet on thrombus formation. For the most part, exploration of this problem has been indirect; in the first place, it has been supposed that in vitro tests of coagulation are good measures of the coagulant activity of the blood and t...

Synchronization properties of fully connected networks of identical oscillatory neurons are studied, assuming purely excitatory interactions. We analyze their dependence on the time course of the synaptic interaction and on the response of the neurons to small depolarizations. Two types of responses are distinguished. In the first type, neurons always respond to small depolarization by advancin...

The evolution of cooperation has played an important role in evolutionary biology over the last 40 years. There is a broad consensus thatHamilton’s theory of kin selection (Hamilton, 1964) provides a basis for understanding the deployment of altruism among relatives in a wide range of animal taxa (Crozier and Pamilo, 1996; Dugatkin, 1997; Emlen, 1997; Sachs et al., 2004). In contrast, there is ...

The speech of individuals with Parkinson's Disease (PD) is characterized by reduced stress, increased rate, monotonic pitch and loudness and imprecise consonant production (see Darley, Aronson, & Brown, 1975 for review). Acoustically, speech has decreased duration of voiced segments, reduced fundamental frequency variations and limited formant trajectories at consonant-vowel transitions as comp...

The somata of molluscan neurones respond with long trains of spikes to steady injected outward current. During such repetitive firing the maximum rate of rise of action potentials usually decreases as a result of inactivation of the transport mechanism for inward current. Significant inactivation of this transport system does not often change the peak level of the action potential (Magura, 1967...

Abstract Date Presented 04/22/2023 This study explores how social support mediates the relationship between an individual’s abilities and their participation. Results indicate that is a mediator for people with aphasia to participate in cognitively demanding activities.
