There is evidence against the presence of a functional accessory olfactory bulb in humans and other higher primates.

Encoding pheromonal signals in the accessory olfactory bulb of behaving mice.

Accessory olfactory bulb, the dorsal-posterior region of the main olfactory bulb.

The vomeronasal cells report to a distinct region of the olfactory bulb known as the accessory olfactory bulb.

The second set of nerves, Dr. Stensaas said, are the vomeronasal neurons, which pass through a structure called the accessory olfactory bulb.

The bulb is divided into two distinct structures: the main olfactory bulb and the accessory olfactory bulb.

As in the main olfactory bulb, axonal input to the accessory olfactory bulb forms synapses with mitral cells within glomeruli.

However, mitral cells in the accessory olfactory bulb project their axons to targets in the amygdala and hypothalamus, where they may influence aggressive and mating behavior.

From the accessory olfactory bulb, information is sent to the amygdala, which handles emotions, and then to the hypothalamus, which handles basic body functions and metabolic processes.

It is the first processing stage of the accessory olfactory system, after which chemical stimuli go to the accessory olfactory bulb, then to targets in the amygdala and hypothalamus.

The accessory olfactory bulb, which resides on the dorsal-posterior region of the main olfactory bulb, forms a parallel pathway independent from the main olfactory bulb.

The pheromonal information travels via nerves to the accessory olfactory bulb, and then to the corticomedial amygdala, accessory olfactory tract, and stria terminalis.

In vertebrates, Slit1 plays an important role in vomeronasal organ (VNO) axonal targeting to the accessory olfactory bulb (AOB).

The axons from these neurons project to the accessory olfactory bulb, which targets the amygdala and bed nucleus of the stria terminalis, which in turn project to the hypothalamus.

There is also a modified accessory olfactory bulb at the base of the principal one, which is associated specifically to incoming afferents from Jacobson's organ found at the nasal septum.

The vomeronasal receptor neurons possess axons which travel from the VNO to the accessory olfactory bulb (AOB) or, as its also known, the vomeronasal bulb.

Accessory olfactory cortical areas are portions of the human amygdala that are homologous to those areas in other species that receive afferents from the accessory olfactory bulb.

But the accessory olfactory bulb bypasses the higher centers, sending its fibers to the amygdala, an area of emotional control, and from there to the hypothalamus, a control region for the body's hormones.

Activating neurons that have V1 receptors, V1Rs, cause field potentials that have weak, fluctuating responses that are seen the anterior of the accessory olfactory bulb, AOB.

Likewise, there is no evidence for any accessory olfactory bulb in adult human beings, and the key genes involved in VNO function in other mammals have pseudogeneized in human beings.

However, if the pheromones correspond with those memorised by the female (usually the male mating partner), a release of noradrenaline will lower the receptivity of the accessory olfactory bulb to these pheromones.

Paleocortex is present in the parahippocampal gyrus, olfactory bulb, accessory olfactory bulb, olfactory tubercle, piriform cortex, periamygdalar area, anterior olfactory nucleus, anterior perforated substance, and prepyriform area.

Fluids traveling from the rhinarium to the mouth and then up the nasopalatine ducts to the VNO are detected, and information is relayed to the accessory olfactory bulb, which is relatively large in strepsirrhines.

Research with a variety of animals suggest the role of norepinephrine in olfactory learning, in which norepinephrine neurons in the locus coeruleus send projections to neurons in the main and accessory olfactory bulbs.

For the group in which vomeronasal perception was rendered inactive, the vomeronasal nerves only were severed; this was later confirmed by use of both an anterograde tracer and postmortem examination of the accessory olfactory bulb.
