Neurobiology of taste-recognition memory formation.
Recognition memory is the ability to assert the familiarity of things previously encountered. In the case of food, when an animal encounters a new taste, it hesitates to eat it, showing a reduced consumption—a neophobic response. However, when the new taste has no negative consequences, it becomes recognized as a safe signal, leading to an increase in its consumption (attenuation of neophobia)....
متن کاملPerirhinal cortex muscarinic receptor blockade impairs taste recognition memory formation.
The relevance of perirhinal cortical cholinergic and glutamatergic neurotransmission for taste recognition memory and learned taste aversion was assessed by microinfusions of muscarinic (scopolamine), NMDA (AP-5), and AMPA (NBQX) receptor antagonists. Infusions of scopolamine, but not AP5 or NBQX, prevented the consolidation of taste recognition memory using attenuation of neophobia as an index...
متن کاملTaste memory formation: role of nucleus accumbens.
When a novel taste has been associated with postingestive malaise, animals recognize this taste as aversive. This associative learning is known as conditioned taste aversion. However, when an animal consumes a novel taste and no aversive consequences follow, it becomes recognized as a safe signal, leading to an increase in its consumption in subsequent presentations. In this review, we will dis...
متن کاملThe Neurobiology of Taste and Smell
One day clinical neurologists will wake up to the fact that within the special senses of smell and taste lays an ocean of undiscovered information much of which will be relevant to our understanding of common neurological illness, especially of the degenerative variety. Inevitably the majority of writing on smell and taste is in the non-human domain and this book is no exception. Of the 24 cont...
متن کاملRedundant basal forebrain modulation in taste aversion memory formation.
Mnemonic deficits resulting from excitotoxic lesion of the basal forebrain have been classically attributed to the resulting depletion of cortical acetylcholine activity. It has been demonstrated that in spite of the strong cholinergic depletion after injections into the basal forebrain of the immunotoxin 192IgG-saporin, no detectable deficit can be found in the acquisition of several learning ...
