Here we demonstrate a qualitative, region-specific difference in the organization of mouse corticothalamic pathways. Specifically, L5 pyramidal cells of the frontal cortex, but not other cortical regions, establish monosynaptic connections with the inhibitory thalamic reticular nucleus (TRN). The frontal L5–TRN pathway parallels the L6–TRN projection but has distinct morphological and physiological features. The exact spike output of the L5-contacted TRN cells correlated with the level of cortical synchrony. Optogenetic perturbation of the L5–TRN connection disrupted the tight link between cortical and TRN activity. L5-driven TRN cells innervated thalamic nuclei involved in the control of frontal cortex activity.

Here we demonstrate that the calretinin (CR)-containing neurons in the dorsal medial thalamus (DMT) constitute a key diencephalic node that mediates distinct levels of forebrain arousal. Cell-type-specific activation of DMT/CR+ cells elicited active locomotion lasting for minutes, stereotyped microarousals, or transient disruption of sleep rhythms, depending on the parameters of the stimulation. State transitions could be induced in both slow-wave and rapid eye-movement sleep. The DMT/CR+ cells displayed elevated activity before arousal, received selective subcortical inputs, and innervated several forebrain sites via highly branched axons. Together, these features enable DMT/CR+ cells to summate subcortical arousal information and effectively transfer it as a rapid, synchronous signal to several forebrain regions to modulate the level of arousal. © 2018, The Author(s), under exclusive licence to Springer Nature America, Inc.}, year = {2018}, eissn = {1546-1726}, pages = {1551-1562}, orcid-numbers = {Mátyás, Ferenc/0000-0002-3903-8896; Babiczky, Ákos/0000-0001-5848-7374; Kanti, Vivien Ildikó/0000-0003-4715-3883; Magyar, Aletta/0000-0002-2644-4182} } @article{MTMT:3398238, title = {Heartless beat or beatless heart?}, url = {https://m2.mtmt.hu/api/publication/3398238}, author = {Acsády, László}, doi = {10.1038/s41593-018-0140-2}, journal-iso = {NAT NEUROSCI}, journal = {NATURE NEUROSCIENCE}, volume = {21}, unique-id = {3398238}, issn = {1097-6256}, year = {2018}, eissn = {1546-1726}, pages = {649-651} } @article{MTMT:3356704, title = {Synaptic scaling in sleep}, url = {https://m2.mtmt.hu/api/publication/3356704}, author = {Acsády, László and Harris, KD}, doi = {10.1126/science.aam7917}, journal-iso = {SCIENCE}, journal = {SCIENCE}, volume = {355}, unique-id = {3356704}, issn = {0036-8075}, year = {2017}, eissn = {1095-9203}, pages = {457-457} } @article{MTMT:3356700, title = {The thalamic paradox.}, url = {https://m2.mtmt.hu/api/publication/3356700}, author = {Acsády, László}, doi = {10.1038/nn.4583}, journal-iso = {NAT NEUROSCI}, journal = {NATURE NEUROSCIENCE}, volume = {20}, unique-id = {3356700}, issn = {1097-6256}, year = {2017}, eissn = {1546-1726}, pages = {901-902} } @article{MTMT:3341635, title = {Distinct Thalamic Reticular Cell Types Differentially Modulate Normal and Pathological Cortical Rhythms}, url = {https://m2.mtmt.hu/api/publication/3341635}, author = {Clemente-Perez, A and Makinson, SR and Higashikubo, B and Brovarney, S and Cho, FS and Urry, A and Holden, SS and Wimer, M and Dávid, Csaba and Fenno, LE and Acsády, László and Deisseroth, K and Paz, JT}, doi = {10.1016/j.celrep.2017.05.044}, journal-iso = {CELL REP}, journal = {CELL REPORTS}, volume = {19}, unique-id = {3341635}, issn = {2211-1247}, abstract = {Integrative brain functions depend on widely distributed, rhythmically coordinated computations. Through its long-ranging connections with cortex and most senses, the thalamus orchestrates the flow of cognitive and sensory information. Essential in this process, the nucleus reticularis thalami (nRT) gates different information streams through its extensive inhibition onto other thalamic nuclei, however, we lack an understanding of how different inhibitory neuron subpopulations in nRT function as gatekeepers. We dissociated the connectivity, physiology, and circuit functions of neurons within rodent nRT, based on parvalbumin (PV) and somatostatin (SOM) expression, and validated the existence of such populations in human nRT. We found that PV, but not SOM, cells are rhythmogenic, and that PV and SOM neurons are connected to and modulate distinct thalamocortical circuits. Notably, PV, but not SOM, neurons modulate somatosensory behavior and disrupt seizures.

Thalamic circuits are targeted by two major inhibitory systems: the thalamic reticular nucleus (TRN) and extrathalamic inhibitory (ETI) inputs. A unifying framework of how these systems operate is currently lacking. Here, we propose that TRN circuits are specialized to exert thalamic control at different spatiotemporal scales. Local inhibition of thalamic spike rates prevails during attentional selection, whereas global inhibition more likely prevails during sleep. In contrast, the ETI (arising from basal ganglia, zona incerta (ZI), anterior pretectum, and pontine reticular formation) provides temporally precise and focal inhibition, impacting spike timing. Together, these inhibitory systems allow graded control of thalamic output, enabling thalamocortical operations to dynamically match ongoing behavioral demands.}, year = {2016}, eissn = {1878-108X}, pages = {680-693} }
