  • neuropil
  • We show that the density in microglomeruli increases as a specific olfactory LTM is formed, while the volume of the neuropil remains constant. (jneurosci.org)
  • As a result of these processes, the mushroom body calyx neuropil volume enlarges while the total number of microgloumeruli becomes reduced in foragers compared to indoor workers. (uni-wuerzburg.de)
  • axons
  • The assembly of the fly olfactory system requires precise glomerular targeting of axons from each of the 50 ORN classes, as well as dendrites of each of the 50 PN classes. (stanford.edu)
  • behavior
  • However, to fully elucidate the neural circuitry of complex behavior, it is crucial to understand brain interactions with the whole body, which can be achieved only by mapping the whole-body connectome. (jneurosci.org)
  • Kenyon
  • We showed that the neurites of Kenyon cells with cell bodies located in a neighborhood in calyx retain their relative neighborhoods in the pedunculus and the vertical lobe forming a columnar organization in the mushroom body. (springer.com)
  • In particular, connection probability ½, as found in the locust antennal-lobe-mushroom-body circuit, serves to maximize separation of neuronal representations across the target Kenyon cells (KCs), and explains their specific and reliable responses. (frontiersin.org)
  • memory
  • Hymenoptera possess voluminous mushroom bodies (MBs), brain centres associated with sensory integration, learning and memory. (royalsocietypublishing.org)
  • When relating volumes of brain centres to cognitive capacities, it becomes particularly interesting to quantify brain centres involved in learning and memory, such as the insect mushroom bodies (MBs) [ 10 - 15 ]. (royalsocietypublishing.org)
  • We found that the species was amenable to olfactory conditioning and showed good learning and memory retention at 24 h after training. (springer.com)
  • We identified 10 genes that enhance or decrease memory when knocked-down in the mushroom body. (genetics.org)
  • because the cricket has relatively short life-cycle and a high capability of olfactory learning and memory. (frontiersin.org)
  • however they showed significantly decreased levels of 1-day retention, indicating AMI in long-term memory (LTM) but not in anesthesia-resistant memory (ARM) in olfactory learning of crickets. (frontiersin.org)
  • The formation of olfactory memory is a multistage process that involves different areas of the insect brain. (biologists.org)
  • By contrast, PN axon terminal arborizations in the mushroom body, the olfactory learning and memory center, exhibit much less stereotypy. (stanford.edu)
  • Using a combination of knockdown by RNA interference and pharmacological manipulation, we disrupted the function of CaMKII during olfactory learning and memory formation. (biologists.org)
  • Here we concentrate on honeybees by demonstrating a unique extracellular long term access to record multi unit activity at two subsequent neuropiles 1 , the antennal lobe (AL), the first olfactory processing stage and the mushroom body (MB), a higher order integration center involved in learning and memory formation, or two parallel neuronal tracts 2 connecting the AL with the MB. (jove.com)
  • They are thought to be involved in olfactory learning and memory. (jove.com)
  • locust
  • Inspired by experimental findings on network architecture in the olfactory system of the locust, I construct a highly simplified theoretical framework which allows for analytic solution of its key properties. (frontiersin.org)

  • Brain
  • The total brain volume and absolute volumes of olfactory mushroom body subdivisions were positively correlated with head widths, but mini workers had significantly larger MB to total brain ratios. (royalsocietypublishing.org)
  • Most recent projects focus on only brain neurons, with the exception of an early effort to reconstruct the 302 neurons that comprise the whole body of the small worm, Caenorhabditis elegans . (jneurosci.org)
  • the brain cannot function in isolation from interactions with the external environment and other internal body parts. (jneurosci.org)
  • Here, we review the current technologies available for mapping the brain connectome and discuss the challenges associated with mapping whole-body connectomes. (jneurosci.org)

  • These studies suggest that the biogenic amine octopamine (OA) represents the occurrence of sucrose in brain networks that process olfactory inputs. (springer.com)
  • insects
  • The intimate relationship between insects and plants relies to a large extent on plant produced chemical cues and sophisticated olfactory and gustatory systems evolved in insects. (frontiersin.org)
  • honeybees
  • We found that honeybees were only able to differentiate between different pollen types, when they could use both chemotactile and olfactory cues. (uni-wuerzburg.de)
  • cues
  • Whether they rely on visual, olfactory and/or chemotactile cues to distinguish between different pollen types, has however been little studied. (uni-wuerzburg.de)
