Taste Aversion Learning Despite Long Delays: How Best Explained?

Molecular signaling during taste aversion learning.

Behavioral and neural assessment tools have been used to identify cellular and molecular events that occur during taste aversion acquisition. Studies described here include an assessment of taste information processing and taste-illness association using fos-like immunoreactivity (FLI) to mark populations of cells that react strongly to the taste conditioned stimulus (CS), the illness unconditi...

"Learned safety" as a mechanism in long-delay taste-aversion learning in rats.

Rats learn taste aversions with unusually long CS-US delays. This has previously been explained as slow decay of a CS trace or as relative lack of interference. We propose, however, that the CS-US delay gradient is a learning curve: During the delay, a rat gradually learns that a taste is "safe." A solution which a rat drinks only once becomes safe and resistant to learned aversions for at leas...

Taste-aversion Learning and Its Implications for Rodent Control

Although bait shyness has long been recognized as a problem to be overcome in the control of vertebrate pests, it has recently been suggested that the phenomenon might be turned to an advantage and used as an alternative, non-lethal form of control. Unfortunately, this technique has not proven to be as useful as hoped, as the work which has been done on coyotes is inconclusive at best and some ...

Amiloride is an ineffective conditioned stimulus in taste aversion learning.

The present study demonstrated that 100 microM amiloride serves as an ineffective conditioned taste stimulus in a taste aversion paradigm. Even if amiloride has a detectable taste, it's unlikely that its behavioral effects in salt mixture experiments are due to its inherent taste quality.
