609:(GABA). As a result of its bi-directionality, the dendro-dendritic synapse can cause mitral cells to inhibit themselves (auto-inhibition), as well as neighboring mitral cells (lateral inhibition). More specifically, the granule cell layer receives excitatory glutamate signals from the basal dendrites of the mitral and tufted cells. The granule cell in turn releases GABA to cause an inhibitory effect on the mitral cell. More neurotransmitter is released from the activated mitral cell to the connected dendrite of the granule cell, making the inhibitory effect from the granule cell to the activated mitral cell stronger than the surrounding mitral cells. It is not clear what the functional role of lateral inhibition would be, though it may be involved in boosting the signal-to-noise ratio of odor signals by silencing the basal firing rate of surrounding non-activated neurons. This in turn aids in odor discrimination. Other research suggest that the lateral inhibition contributes to differentiated odor responses, which aids in the processing and perception of distinct odors. There is also evidence of cholinergic effects on granule cells that enhance depolarization of granule cells making them more excitable which in turn increases inhibition of mitral cells. This may contribute to a more specific output from the olfactory bulb that would closer resemble the glomerular odor map. Olfaction is distinct from the other 532:. Neural firing varies temporally, there are periods of fast, spontaneous firing and slow modulation of firing. These patterns may be related to sniffing or change in intensity and concentration of odorant. Temporal patterns may have effect in later processing of spatial awareness of odorant. For example, synchronized mitral cell spike trains appear to help to discriminate similar odors better than when those spike trains are not synchronized. A well known model is that the bulbar neural circuit transforms the odor information in the receptors to a population pattern of neural oscillatory activities in the mitral cell population, and this pattern is then recognized by the associative memories of olfactory objects in the olfactory cortex. Top-down feedback from the olfactory cortex to the olfactory bulb modulates the bulbar responses, so that, for example, the bulb can adapt to a pre-existing olfactory background to single out a foreground odor from an odor mixture for recognition, or can enhance sensitivity to a target odor during odor search. Destruction to the olfactory bulb results in 670:
sensory neurons in detecting chemical stimuli of different type and molecular weight. Although it doesn't seem to be maintained centrally, where mitral cell projections from both sides of the AOB converge. A clear difference of the AOB circuitry, compared to the rest of the bulb, is its heterogeneous connectivity between mitral cells and vomeronasal sensory afferents within neuropil glomeruli. AOB mitral cells indeed contact through apical dendritic processes glomeruli formed by afferents of different receptor neurons, thus breaking the one-receptor-one-neuron rule which generally holds for the main olfactory system. This implies that stimuli sensed through the VNO and elaborated in the AOB are subjected to a different and probably more complex level of elaboration. Accordingly, AOB mitral cells show clearly different firing patterns compared to other bulbar projection neurons. Additionally, top down input to the olfactory bulb differentially affects olfactory outputs.
721:. The odors serve as the reinforcers or the punishers during the associative learning process; odors that occur with positive states reinforce the behavior that resulted in the positive state while odors that occur with negative states do the opposite. Odor cues are coded by neurons in the amygdala with the behavioral effect or emotion that they produce. In this way odors reflect certain emotions or physiological states. Odors become associated with pleasant and unpleasant responses, and eventually the odor becomes a cue and can cause an emotional response. These odor associations contribute to emotional states such as fear. Brain imaging shows amygdala activation correlated with pleasant and unpleasant odors, reflecting the association between odors and emotions. 53: 806:
periglomerular cell interneurons that reside in the granule cell layer and glomerular layers, respectively. The olfactory sensory neuron axons that form synapses in olfactory bulb glomeruli are also capable of regeneration following regrowth of an olfactory sensory neuron residing in the olfactory epithelium. Despite dynamic turnover of sensory axons and interneurons, the projection neurons (mitral and tufted neurons) that form synapses with these axons are not structurally plastic.
313: 836: 188: 521:, many researchers have focused on how the olfactory bulb filters incoming information from receptor neurons in space, or how it filters incoming information in time. At the core of these proposed filters are the two classes of interneurons; the periglomerular cells, and the granule cells. Processing occurs at each level of the main olfactory bulb, beginning with the spatial maps that categorize odors in the glomeruli layer. 29: 895:, have produced similarly large-brained human species. Thus, understanding human brain evolution should include research into specific cerebral reorganization, possibly reflected by brain shape changes. Here we exploit developmental integration between the brain and its underlying skeletal base to test hypotheses about brain evolution in 759:. Olfactory bulb removal in rats effectively causes structural changes in the amygdala and hippocampus and behavioral changes similar to that of a person with depression. Researchers use rats with olfactory bulbectomies to research antidepressants. Research has shown that removal of the olfactory bulb in rats leads to 746:
