Olfaction, or the sense of smell, is facilitated by specialized sensory cells, called olfactory sensory neurons, which are directly connected directly to the brain.
The limbic system is a set of brain structures located on both sides of the thalamus.
The limbic circuitry supports a variety of functions, including emotion, behavior, motivation, long-term memory, and olfaction.
The olfaction bulb is connected to the amygdala and the hippocampus.
The anterior limbic and related structures including the orbitofrontal cortex and amygdala are involved in emotion, reward valuation, and reward-related decision-making (but not memory), with the value representations transmitted to the anterior cingulate cortex for action-outcome learning. (Rolls, Edmund T. 2015)
Olfaction and executive measures have a common neural substrate in prefrontal and orbitofrontal cortex, and suggest that olfaction might be a reliable cognitive marker in psychiatric and neurologic disorders. (Fagundo, A. B. 2015)
Activation of emotional neural substrates might alter the dual cognitive dorsolateral prefrontal cortex and emotional orbital prefrontal cortex circuits that interact during decision-making. (Overman, W.H. 2011)
Sex-related performance differences on this task: males perform significantly better than females on decision-making in the Iowa Gambling Task. (Reavis and Overman, 2001)
