Suppressive Competition: How Sounds May Cheat Sight
نویسندگان
چکیده
In this issue of Neuron, Iurilli et al. (2012) demonstrate that auditory cortex activation directly engages local GABAergic circuits in V1 to induce sound-driven hyperpolarizations in layer 2/3 and layer 6 pyramidal neurons. Thereby, sounds can directly suppress V1 activity and visual driven behavior.

The isthmo-optic nucleus: : A possible neural substrate for visual competition
Birds have a well-developed centrifugal pathway from the optic tectum to the retina via the isthmo-optic nucleus (ION). Receptive fields of the isthmo-optic (IO) neurons have a wide suppressive field extending to, at least, two-thirds of the entire visual field of a singe eye. Such wide suppressive fields indicate that the IO neurons may compete with each other for activity in a very long-range...
متن کاملIn vivo suppression of naive CD4 T cell responses by IL-2- and antigen-stimulated T lymphocytes in the absence of APC competition.
After stimulation, T cells enter a transient refractory period, promoted by IL-2, during which they are resistant to re-stimulation. We previously demonstrated that these IL-2- and Ag-stimulated refractory T cells are able to suppress the Ag-induced proliferation of naive T cells in vitro. We show here that, after adoptive transfer, these T cells are also able to suppress naive T cell prolifera...
متن کاملA Synchrony-Dependent Influence of Sounds on Activity in Visual Cortex Measured Using Functional Near-Infrared Spectroscopy (fNIRS)
Evidence from human neuroimaging and animal electrophysiological studies suggests that signals from different sensory modalities interact early in cortical processing, including in primary sensory cortices. The present study aimed to test whether functional near-infrared spectroscopy (fNIRS), an emerging, non-invasive neuroimaging technique, is capable of measuring such multisensory interaction...
متن کاملCheating in Exams with Technology
Traditional methods of detection may no longer be wholly successful in fully preventing cheating in examinations. New strategies need to be considered and employed to better manage the advancement of technology use for illegitimate purposes. This paper investigates technology used to cheat in examinations, how such cheats are carried out, and how to prevent such methods of cheating. To show the...
متن کاملCan Knowledge Management Help in Poverty-stricken Countries and Crisis Situations
At first sight, knowledge management for poverty-stricken countries appears to be a contradiction in terms. It sounds "high-tech" and not very applicable for "third world" countries that may not possess the necessary infrastructure. However, the aim of the paper is to show that this is not only false but that Knowledge Management (KM) has a big role to play. We begin by giving an introduction t...
