Although brain tissue is usually cut at ice-cold temperature (CT) to facilitate slicing and avoid neuronal damage, exposure to CT causes molecular and architectural changes of synapses. To address these issues, we investigated ultrastructural and electrophysiological features of synapses in mouse acute cerebellar slices prepared at ice-cold and physiological temperature (PT). In the slices prepared at CT, we found significant spine loss and reconstruction, synaptic vesicle rearrangement and decrease in synaptic proteins, all of which were not detected in slices prepared at PT. Consistent with these structural findings, slices prepared at PT showed higher release probability. Furthermore, preparation at PT allows electrophysiological recording immediately after slicing resulting in higher detectability of long-term depression (LTD) after motor learning compared with that at CT. These results indicate substantial advantages of the slice preparation at PT for investigating synaptic functions in different physiological conditions."}],"department":[{"_id":"JoDa"},{"_id":"RySh"}],"day":"19","file":[{"file_id":"7668","file_size":9227283,"date_created":"2020-04-20T10:59:49Z","date_updated":"2020-07-14T12:48:01Z","content_type":"application/pdf","access_level":"open_access","creator":"dernst","file_name":"2020_FrontiersCellularNeurosc_Eguchi.pdf","checksum":"1c145123c6f8dc3e2e4bd5a66a1ad60e","relation":"main_file"}],"type":"journal_article","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_updated":"2023-08-21T06:12:48Z","article_processing_charge":"Yes (via OA deal)","month":"03","isi":1,"file_date_updated":"2020-07-14T12:48:01Z","ddc":["570"],"project":[{"_id":"2659CC84-B435-11E9-9278-68D0E5697425","name":"Ultrastructural analysis of phosphoinositides in nerve terminals: distribution, dynamics and physiological roles in synaptic transmission","grant_number":"793482","call_identifier":"H2020"},{"name":"In situ analysis of single channel subunit composition in neurons: physiological implication in synaptic plasticity and behaviour","_id":"25CA28EA-B435-11E9-9278-68D0E5697425","grant_number":"694539","call_identifier":"H2020"},{"call_identifier":"FWF","_id":"265CB4D0-B435-11E9-9278-68D0E5697425","name":"Optical control of synaptic function via adhesion molecules","grant_number":"I03600"},{"name":"IST Austria Open Access Fund","_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854"}],"volume":14,"intvolume":"        14","year":"2020","ec_funded":1,"citation":{"ieee":"K.
