These patterns are robustly observed in sensory cortex30,38,39,44,45,46,47,48,49 (Fig. 5a). Differences in granular layer (L4) synaptic activation as a function of oddball vs. distractor stimulation thus would indicate feedforward oddball signaling. Analyzing the fastest reaction time trials, ...
1.1Sensory Cortex Sensory cortexrefers to all cortical areas associated with sensory function. In the case of vision, this includes virtually all of theoccipital cortexand much of the temporal andparietal cortex. An object must be perceived before it can be categorized, so an intact sensory cortex...
Brain function: changing ideas on the role of sensory, motor, and associa- tion cortex in behavior. Annu Rev Psychol. 1974; 25:277-312. Epub 1974/01/01. PMID: 4205693Masterton RB, Berkley MA: Brain function: changing ideas on the role of sensory, motor, and association cortex in ...
Intracortical microstimulation of the somatosensory cortex evokes tactile sensations, but those of individual electrodes are insufficient for functional tasks. We show that stimulating multiple electrodes with somatotopically matched projected fields improves task performance with bionic hands. ...
1B). In the cochlea, the stereocilia of a hair bundle are arranged in order of increasing height toward the edge of the apical cortex to form a “V”-shaped structure with a single primary cilium, known as the kinocilium, placed near the tallest stereocilia at the vertex of the “V...
Pre-attentive auditory sensory gating (SG), an attenuated neural activation to the second identical stimulus, has been found to be related to the performance of higher-hierarchical brain function. However, it remains unclear whether other cortical regions, such as somatosensory cortex, also possess ...
Our efforts to understand the function of sensory systems have been aided by the development of new techniques, including powerful methods of molecular biology, refined short- and long-term approaches to recording from single and multiple neurons, and non-invasive neuroimaging techniques that allow us...
changing the brain, which changes the mind and the body. In Sternberg’s love triad, commitment, the active decision to stay in the relationship, represents the brain. A connection to people’s evolved pre-frontal cortex and executive function skills such as goal-directed or task-directed persi...
