Olfactory Computations and Network Oscillations
Oscillatory activity is a universal design feature of olfactory systems (Tank et al., 1994), having been demonstrated by Lord Adrian in the olfactory bulb of the hedgehog 60 years ago (Adrian, 1942). Hints as to the computational role of olfactory oscillations have only recently begun to emerge (Stopfer et al., 1997; Teyke and Gelperin, 1999; Nusser et al., 2001) (but see Fletcher et al., 2005)...
متن کاملOlfactory maps, circuits and computations.
Sensory information in the visual, auditory and somatosensory systems is organized topographically, with key sensory features ordered in space across neural sheets. Despite the existence of a spatially stereotyped map of odor identity within the olfactory bulb, it is unclear whether the higher olfactory cortex uses topography to organize information about smells. Here, we review recent work on ...
متن کاملOlfactory consciousness and gamma oscillation couplings across the olfactory bulb, olfactory cortex, and orbitofrontal cortex
The orbitofrontal cortex receives multi-modality sensory inputs, including olfactory input, and is thought to be involved in conscious perception of the olfactory image of objects. Generation of olfactory consciousness may require neuronal circuit mechanisms for the "binding" of distributed neuronal activities, with each constituent neuron representing a specific component of an olfactory perce...
متن کاملA beta oscillation network in the rat olfactory system during a 2-alternative
26 27 We previously showed that in a 2-alternative choice (2AC) task, olfactory bulb (OB) 28 gamma oscillations (~70 Hz in rats) were enhanced during discrimination of structurally 29 similar odorants (fine discrimination) vs. discrimination of dissimilar odorants (coarse 30 discrimination). In other studies (mostly employing go/no-go tasks) in multiple labs, beta 31 oscillations (15-35 Hz) dom...
متن کاملConnectivity and computations in higher-order olfactory neurons in Drosophila
Understanding how odors are encoded in the brain is of fundamental importance to neurobiology. The first two stages of olfactory information processing have been relatively well studied in both vertebrates and invertebrates. However, the organizational principles of higher order olfactory representations remain poorly understood. Neurons in the first relay of the olfactory system segregate into...
