Specifically, they contain mechanosensory femoral chordotonal organs (FeCO) that monitor femorotibial movements and mediate behaviours ranging from local leg reflexes to whole-body movements. The structure and material properties of FeCO prefilter incoming mechanical signals, which are encoded by the underlying mechanosensory neurons. FeCO consists of functionally specialised subunits within which pairs of neurons are organised into scolopidia that connect to tibia via a receptor apodeme, an invagination of the tibial cuticle. In some hemimetabolous insects, the apodeme connects to individual scolopidia at different points, activating them at different tibial positions and mechanically fractionating the stimulus range. However, in some holometabolous insects, mechanical stimulus is channelled into different components and directed to various FeCO subunits. FeCO thus serves as an ideal mechanosensory organ to study the role of structure in determining sensory function.</div></div>","PeriodicalId":56191,"journal":{"name":"Current Opinion in Behavioral Sciences","volume":"60 ","pages":"Article 101459"},"PeriodicalIF":4.9,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142705755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we review recent studies investigating dopamine signals in simple and complex forms of perceptual decision tasks across species and dopaminergic circuits. We discuss how reinforcement learning (RL) models can account for key aspects of learning during perceptual decision making and its dopaminergic underpinnings, thus bridging the gap with the literature on dopamine in value-based decisions.

On top of this synaptic ‘chassis’ of nervous systems, neuropeptides and hormones have traditionally been considered as slow neuromodulatory signals that fine-tune synaptic circuits. However, neuropeptides can generate many behaviors, including quite complex ones, from cnidarians to humans. Moreover, neuropeptide actions span larger temporal scales than fast synaptic transmission and are thus better matched to behavioral time courses than synaptic circuits. Furthermore, in some metazoans, the effects of neuropeptides are independent of synaptic connectivity, and in many species, the systemic application of neuropeptides can trigger selective behaviors. Based on this, we argue that nonsynaptic neuropeptide signaling via chemical networks — forming a ‘chemical’ connectome — represents the ancestral mechanism to encode behavioral sequences, whereas synaptic networks co-evolved as a specialization complementing chemical networks in the control of behaviors and computational functions.</div></div>","PeriodicalId":56191,"journal":{"name":"Current Opinion in Behavioral Sciences","volume":"60 ","pages":"Article 101456"},"PeriodicalIF":4.9,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142536106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
