Octopus Conditioning: A Multi-Armed Approach to the LTP–Learning Question
نویسنده
چکیده
A recent study shows that avoidance conditioning in the cephalopod Octopus vulgaris is mediated by long-term potentiation (LTP), a form of synaptic plasticity thought to be important in vertebrate associative learning. Thus, LTP appears to be an evolutionarily conserved learning mechanism.

متن کاملThe Octopus Vertical Lobe Modulates Short-Term Learning Rate and Uses LTP to Acquire Long-Term Memory
Analyzing the processes and neuronal circuitry involved in complex behaviors in phylogenetically remote species can help us understand the evolution and function of these systems. Cephalopods, with their vertebrate-like behaviors but much simpler brains, are ideal for such an analysis. The vertical lobe (VL) of Octopus vulgaris is a pivotal brain station in its learning and memory system. To ex...
متن کاملObservational Learning in Octopus vulgaris.
Untrained Octopus vulgaris (observers) were allowed to watch conditioned Octopus(demonstrators) perform the task of selecting one of two objects that were presented simultaneously and differed only in color. After being placed in isolation, the observers, in a similar test, consistently selected the same object as did the demonstrators. This learning by observation occurred irrespective of the ...
متن کاملA learning and memory area in the octopus brain manifests a vertebrate-like long-term potentiation.
Cellular mechanisms underlying learning and memory were investigated in the octopus using a brain slice preparation of the vertical lobe, an area of the octopus brain involved in learning and memory. Field potential recordings revealed long-term potentiation (LTP) of glutamatergic synaptic field potentials similar to that in vertebrates. These findings suggest that convergent evolution has led ...
متن کاملLong-term potentiation in the amygdala: a cellular mechanism of fear learning and memory.
Much of the research on long-term potentiation (LTP) is motivated by the question of whether changes in synaptic strength similar to LTP underlie learning and memory. Here we discuss findings from studies on fear conditioning, a form of associative learning whose neural circuitry is relatively well understood, that may be particularly suited for addressing this question. We first review the evi...
