Population coding olfaction
WebFibers also project to limbic system, as in olfaction. Cross-fiber theory (aka “population coding”) states that taste quality is represented by the pattern of activity across a population of neurons. Perception. Indentification is poor near threshold sensitivity. Women are better than men at identification. WebOct 9, 2024 · Recent experimental and theoretical work on neural populations belonging to two separate early sensory systems, olfaction and vision, has challenged the notion that the two operate under different computational paradigms by providing evidence for the respective neural population codes having three central, common features: they are highly …
