Sentences with phrase «ventral visual»

Increased spatial variability of the eye movements was associated with widespread increased activity throughout the visual cortex and dorsal and ventral visual processing streams.

In addition I examine implicit memory and adaptation effects using the ventral visual stream as a model system and contrast it with explicit memory and consolidation.

Not exact matches

This suggests that other neurons receive visual signals, compensate for eye movement, then send the processed signal to the ventral intraparietal area.

At the same time, the researchers monitored nerve firing in a part of the cortex — the ventral intraparietal area — that serves as an interface between the brain's visual and motor processing regions.

In one family of experiments, we will use a consistent and comprehensive approach to study how the visual areas of the ventral pathway create visual representations that allow us to recognize and categorize the contents of our visual world.

Seed - based connectivity analyses were conducted to assess differences between groups in 3 default mode network (DMN) components (anterior, posterior, and ventral) and 4 additional non-DMN networks: left and right executive - control, language, and higher visual networks.

Finally, (18) F - labelled fluorodeoxyglucose was similarly reduced in all Alzheimer's disease variants in the dorsal and left ventral default mode network, whereas significant differences were found in the right ventral default mode, right executive - control (both lower in early - onset Alzheimer's disease and posterior cortical atrophy than logopenic variant primary progressive aphasia) and higher - order visual network (lower in posterior cortical atrophy than in early - onset Alzheimer's disease and logopenic variant primary progressive aphasia), with a trend towards lower (18) F - labelled fluorodeoxyglucose also found in the left language network in logopenic variant primary progressive aphasia.

This putative compass - magnetosensory pathway involves restricted subregions at all levels of the thalamofugal visual pathway: neuronal subpopulations in the retina, ventral parts of the thalamic Gld (lateral and ventral DLL, SpRt, LdOPT) and lateral parts of the visual wulst (Cluster N).

In contrast, the DLAmc and dorsal parts of the DLL exclusively showed overlap between tracer from the retina and neurons innervating the medial visual wulst (Fig. 2A, shown in magenta), whereas overlap between retinofugal fibers and neurons projecting only upon Cluster N was observed in ventral parts of the DLL and parts of the LdOPT and SpRt (Fig. 2A, shown in yellow).
