Associative Memory: Without a Trace

Associative 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.

Associative recall of memory without errors.

A neural network which is capable of recalling without errors any set of linearly independent patterns is studied. The network is based on a Hamiltonian version of the model of Personnaz et al. The energy of a state of N (+1}neurons is the square of the Euclidean distance —in phase space— between the state and the linear subspace spanned by the patterns. This energy corresponds to nonlocal upda...

On an Associative Trace for Sentence Memory 1

An associationist model for sentence memory is described that assumes a configuration of independent associations underlies the memory trace for a simple sentence. Thxs is contrasted with a gestalt hypothesis that postulates a unitary trace for the simple sentence. The associationist model, but not the gestalt model, leads to two predictions that were confirmed: (a) incomplete recall of simple ...

Associative learning and memory duration of Trichogramma brassicae

Learning ability and memory duration are two inseparable factors which can increase theefficiency of a living organism during its lifetime. Trichgramma brassice Bezdenko (Hym.:Trichogrammatidae) is a biological control agent widely used against different pest species.This research was conducted to study the olfactory associative learning ability and memoryduration of T. brassicae under laborato...
