A new study reports olfactory bulb neurons in rats use linear summation to make sense of fluctuating odor inputs.
Olfactory retentivity persists at a central level, helping us to identify new odors in complex environments and memorize smells, a new study suggests.
In the olfactory system, tufted cells are better at recognizing smells than mitral cells. Tufted cells are one of two parallel neural circuit loops that help the brain process different odor features. The findings shed light on how the brain takes in sensory information that influences behavior and emotion.
