Frogs have a highly developed nervous system that consists of a brain, spinal cord and nerves. Many parts of frog brains correspond with those of humans. It consists of two olfactory lobes, two cerebral hemispheres, a pineal body, two optic lobes, a cerebellum and a medulla oblongata.
The olfactory bulb (Latin: bulbus olfactorius) is a neural structure of the vertebrate forebrain involved in olfaction, the sense of smell. It sends olfactory information to be further processed in the amygdala, the orbitofrontal cortex (OFC) and the hippocampus where it plays a role in emotion, memory and learning.
The olfactory system, is the sensory system used for the sense of smell (olfaction). Olfaction is one of the special senses directly associated with specific organs. Most mammals and reptiles have a main olfactory system and an accessory olfactory system. The main olfactory system detects airborne substances, while the accessory system senses ...

The lateral horn is the brain region that accomplishes this olfactory information integration. It coordinates behaviors innate (instinctual) behaviors with certain odors. [4] The antennal lobe has two types of neurons that synapse with the olfactory receptor neurons in the antennae and maxillary palps, the local interneurons and projection neurons.
The development of the rhinencephalon varies among species. In humans it is rudimentary. A small area where the frontal lobe meets the temporal lobe and the area of cortex on the uncus of the parahippocampal gyrus (both belonging to the olfactory cortex) have a different structure (so called "allocortex") than most of the telencephalon and are phylogenetically older (so called paleocortex).
Directly associated with the eyes is the optic lobe, as the visual center of the brain. The deutocerebrum processes sensory information from the antennae. [2] [3] It consists of two parts, the antennal lobe and the dorsal lobe. [3] [4] [5] The dorsal lobe also contains motor neurons which control the antennal muscles. [6]
Unlike the main olfactory bulb that sends neuronal signals to the olfactory cortex, the VNO sends neuronal signals to the accessory olfactory bulb and then to the amygdala, BNST, and ultimately hypothalamus. Since the hypothalamus is a major neuroendocrine center (affecting aspects of reproductive physiology and behavior as well as other ...
