Time, trace, memory.
Objections to a trace hypothesis for interval timing do not apply to the multiple-time-scale (MTS) theory, which incorporates a dynamic trace tuned by the system history and can easily accommodate interval timing over a 1,000:1 range. The MTS model can also account for Weber’s law as well as systematic deviations from it. Contrary to our critics, we contend that patterns of variance in interval...
متن کاملAssociative Memory: Without a Trace
Some transient sensory stimuli can cause prolonged activity in the brain. Trace conditioning experiments can reveal the time over which these lasting representations can be utilized and where they reside.
متن کاملMemory trace replay: the shaping of memory consolidation by neuromodulation
The consolidation of memories for places and events is thought to rely, at the network level, on the replay of spatially tuned neuronal firing patterns representing discrete places and spatial trajectories. This occurs in the hippocampal-entorhinal circuit during sharp wave ripple events (SWRs) that occur during sleep or rest. Here, we review theoretical models of lingering place cell excitabil...
متن کاملCREB and neuronal selection for memory trace
Despite considerable progress over the past several decades, our understanding of the mechanisms underlying memory encoding, storage, and expression in a complex neural network are far from complete. In particular, how some neurons rather than others are selectively engaged to encode memory remains largely unknown. Using virus-mediated gene delivery into a small subset of neurons in a given net...
متن کاملTowards an Image of a Memory Trace
ously described in locust PNs (Stopfer and Laurent, 1999). Separate experiments found that honeybee PNs did not show repetitioninduced depression, indicating that the effect is not a generalized run-down. The authors then compared KC activity before and after pairing one odor with sucrose reward and tested how the associative pairing procedure affects KC responses to the rewarded odor (CS+) and...
