Miklashevsky, Alex – Journal of Psycholinguistic Research, 2018
A number of new psycholinguistic variables has been proposed during the last years within embodied cognition framework: modality experience rating (i.e., relationship between words and images of a particular perceptive modality--visual, auditory, haptic etc.), manipulability (the necessity for an object to interact with human hands in order to…

Tong, Michelle T.; Kim, Tae-Young P.; Cleland, Thomas A. – Learning & Memory, 2018
Long-term fear memory formation in the hippocampus and neocortex depends upon brain-derived neurotrophic factor (BDNF) signaling after acquisition. Incremental, appetitive odor discrimination learning is thought to depend substantially on the differentiation of adult-born neurons within the olfactory bulb (OB)--a process that is closely associated…

Huang, Guang-Zhe; Taniguchi, Mutsuo; Zhou, Ye-Bo; Zhang, Jing-Ji; Okutani, Fumino; Murata, Yoshihiro; Yamaguchi, Masahiro; Kaba, Hideto – Learning & Memory, 2018
The formation of mate recognition memory in mice is associated with neural changes at the reciprocal dendrodendritic synapses between glutamatergic mitral cell (MC) projection neurons and GABAergic granule cell (GC) interneurons in the accessory olfactory bulb (AOB). Although noradrenaline (NA) plays a critical role in the formation of the memory,…

König, Christian; Khalili, Afshin; Ganesan, Mathangi; Nishu, Amrita P.; Garza, Alejandra P.; Niewalda, Thomas; Gerber, Bertram; Aso, Yoshinori; Yarali, Ayse – Learning & Memory, 2018
Painful events establish opponent memories: cues that precede pain are remembered negatively, whereas cues that follow pain, thus coinciding with relief are recalled positively. How do individual reinforcement-signaling neurons contribute to this "timing-dependent valence-reversal?" We addressed this question using an optogenetic…

Kumazaki, Hirokazu; Kikuchi, Mitsuru; Yoshimura, Yuko; Miyao, Masutomo; Okada, Ken-ichi; Mimura, Masaru; Minabe, Yoshio – Journal of Autism and Developmental Disorders, 2018
Understanding the nature of olfactory abnormalities is crucial for optimal interventions in children with autism spectrum disorders (ASD). However, previous studies that have investigated odor identification in children with ASD have produced inconsistent results. The ability to correctly identify an odor relies heavily on visual inputs in the…

Dass, Tina K.; Kisamore, April N.; Vladescu, Jason C.; Reeve, Kenneth F.; Reeve, Sharon A.; Taylor-Santa, Catherine – Journal of Applied Behavior Analysis, 2018
Research on tact acquisition by children with autism spectrum disorder (ASD) has often focused on teaching participants to tact visual stimuli. It is important to evaluate procedures for teaching tacts of nonvisual stimuli (e.g., olfactory, tactile). The purpose of the current study was to extend the literature on secondary target instruction and…

Quintana, Gonzalo R.; Jackson, Misha; Nasr, Mojdeh; Pfaus, James G. – Learning & Memory, 2018
Early experiences with sexual reward play a pivotal role in the formation of sexual behavior and partner preference. Associations of salient partner cues, or even neutral cues on a partner, with sexual reward states are a product of Pavlovian learning. However, the extent to which first experiences that associate a neutral stimulus with no…

Quintana, Gonzalo R.; Guizar, Andrés; Rassi, Sarah; Pfaus, James G. – Learning & Memory, 2018
We have shown previously that male rats develop a conditioned ejaculatory preference (CEP) for females scented with a neutral odor like almond or lemon that is paired with the male's post-ejaculatory reward state during their first and subsequent early sexual experiences. However, preexposing males to the neutral odor alone prior to its pairing…

Boisselier, Lise; Ferry, Barbara; Gervais, Rémi – Learning & Memory, 2017
The hippocampal formation has been extensively described as a key component for object recognition in conjunction with place and context. The present study aimed at describing neural mechanisms in the hippocampal formation that support olfactory-tactile (OT) object discrimination in a task where space and context were not taken into account. The…

Richlitzki, Antje; Latour, Philipp; Schwärzel, Martin – Learning & Memory, 2017
Here, we define a role of the cAMP intermediate EPAC in "Drosophila" aversive odor learning by means of null epac mutants. Complementation analysis revealed that EPAC acts downstream from the "rutabaga" adenylyl cyclase and in parallel to protein kinase A. By means of targeted knockdown and genetic rescue we identified mushroom…

Paisios, Emmanouil; Rjosk, Annabell; Pamir, Evren; Schleyer, Michael – Learning & Memory, 2017
Avoiding unfavorable situations is a vital skill and a constant task for any animal. Situations can be unfavorable because they feature something that the animal wants to escape from, or because they do not feature something that it seeks to obtain. We investigate whether the microbehavioral mechanisms by which these two classes of aversion come…

Iacoangeli, Anna; Dosunmu, Aderemi; Eom, Taesun; Stefanov, Dimitre G.; Tiedge, Henri – Learning & Memory, 2017
Dendritic regulatory BC1 RNA is a non-protein-coding (npc) RNA that operates in the translational control of gene expression. The absence of BC1 RNA in BC1 knockout (KO) animals causes translational dysregulation that entails neuronal phenotypic alterations including prolonged epileptiform discharges, audiogenic seizure activity in vivo, and…

Chouhan, Nitin Singh; Wolf, Reinard; Heisenberg, Martin – Learning & Memory, 2017
Starvation causes a motivational state that facilitates diverse behaviors such as feeding, walking, and search. Starved "Drosophila" can form odor/feeding-time associations but the role of starvation in encoding of "time" is poorly understood. Here we show that the extent of starvation is correlated with the fly's ability to…

Ghosh, Abhinaba; Mukherjee, Bandhan; Chen, Xihua; Yuan, Qi – Learning & Memory, 2017
Early odor preference learning occurs in one-week-old rodents when a novel odor is paired with a tactile stimulation mimicking maternal care. ß-Adrenoceptors and L-type calcium channels (LTCCs) in the anterior piriform cortex (aPC) are critically involved in this learning. However, whether ß-adrenoceptors interact directly with LTCCs in aPC…

Elias, Ryan J.; Hopfer, Helene; Hofstaedter, Amanda N.; Hayes, John E. – Journal of Food Science Education, 2017
The human nose is a very sensitive detector and is able to detect potent aroma compounds down to low ng/L levels. These levels are often below detection limits of analytical instrumentation. The following laboratory exercise is designed to compare instrumental and human methods for the detection of volatile odor active compounds. Reference…
