The neuronal architecture of the mushroom body provides a logic for associative learning (2014, background): “…the KCs of the MB comprise 2000 neurons that define only seven distinct cell types, receive unstructured, rather than stereotyped, inputs (Murthy et al., 2008; Caron et al., 2013; Gruntman and Turner, 2013), and connect to multiple MBONs through plastic synapses (Cassenaer and Laurent, 2007, 2012).”
The spike timing dependence of plasticity (2012, background): “Pairing single KC inputs with a suprathreshold current pulse in the b-LN induces synapse-specific, Hebbian STDP of the KC synapse, with LTP occurring for pre-leading-post spike pairings (0 < Dt < 20 ms), and LTD for post-leading-pre pairings ( 20 < Dt < 0 ms) (Cassenaer and Laurent, 2007).”
Functional analysis of a higher olfactory center, the lateral horn (2012, background): “C6 neurons, which also arborize in the -lobe of the MB, have been previously reported as one of the anatomical subtypes of -lobe neurons ( -LNs) belonging to the set of MB output cells (MacLeod et al., 1998; Cassenaer and Laurent, 2007).”
Are mushroom bodies cerebellum-like structures? (2011, background): “…spike-timing dependent plasticity was observed following pairing of Kenyon cell stimulation with efferent neuron depolarization in the locust (Cassenaer and Laurent, 2007), and during olfactory associative conditioning in Drosophila, learning and extinction occurs in the same populations of…”

Encoding of mixtures in a simple olfactory system. (2013, unknown): “Using locusts as models, we gained some understanding of the representation formats for simple odors in the first three relays of its olfactory system—the antennal lobe (AL), mushroom body (MB) and beta lobe (bL)—and of the computations carried out by these circuits (Cassenaer and Laurent, 2007; Maz”
Sleep prevents catastrophic forgetting in spiking neural networks by forming a joint synaptic weight representation (2022, background): “Many of these steps are plastic, in particular decision making circuits utilize spike timing dependent plasticity (STDP) in insects [27] and vertebrates [28,29].”
Conditional modulation of spike-timing-dependent plasticity for olfactory learning (2012, background): “In locusts, the synapses between Kenyon cells and b-lobe neurons (bLNs) are modifiable by a Hebbian STDP rul”
Coherent theta oscillations and reorganization of spike timing in the hippocampal- prefrontal network upon learning. (2010, unknown): “See also Figure S7. have the effect of reinforcing this recently established network by increasing the probability that, within an assembly, the pre- and the postsynaptic spikes of two connected cells fall within a time interval suitable for triggering spike-timing dependent plasticity (STDP) (Markr”
Detrended Fluctuation Analysis: A Scale-Free View on Neuronal Oscillations (2012, background): “It has for a long time been recognized that the brain functions at different time-scales, ranging from a few tens of milliseconds required for the perception of stimuli, to tens of seconds spent on different cognitive operations (Axmacher et al., 2006; Buzsáki, 2006; Cassenaer and Laurent, 2007; Lis”
Heterosynaptic plasticity underlies aversive olfactory learning in Drosophila (2015, unknown): “Then what is known about the learning-related plasticity in this circuit? In other insects, it has been shown that electrical stimulation paradigms can induce plasticity at MB output in locusts (Cassenaer and Laurent, 2007; 2012) and bees (Oleskevich et al.”
Olfactory representations by Drosophila mushroom body neurons. (2008, background): “As the most responsive KC types, ␣Ј/␤Ј neurons might be the ones most likely to experience spike-timing dependent plasticity (Cassenaer and Laurent 2007), which could account for their involvement in memory acquisition.”
Shared Visual Attention and Memory Systems in the Drosophila Brain (2009, background): “The connection between these attention-like oscillations and memory formation would be through spike timing dependent plasticity (STDP) in MB circuits, as has been demonstrated in another insect system [30].”

Spike Timing Dependent Plasticity: A Consequence of More Fundamental Learning Rules (2010, unknown): “A large body of theoretical work now models plasticity in such a manner (Kempter et al., 1999; Song et al., 2000; van Rossum et al., 2000; Rao and Sejnowski, 2001; Gütig et al., 2003; Izhikevich and Desai, 2003; Cassenaer and Laurent, 2007; Fiete et al., 2010).”
Are bigger brains better? (2009, background): “Moreover, connections between neurons show similar plasticity to those found in vertebrates, including short-term, spike-timing-dependent and long-term plasticity [124,125].”
