Mormann, Florian; Liebe, Stefanie; Niediek, Johannes; Reber, Thomas; Faber, Jennifer; Elger, Christian E.; Pals, Matthijs; Macke, Jakob H.; Boström, Jan, 2025, "Phase of firing does not reflect temporal order in sequence memory of humans and recurrent neural networks", https://doi.org/10.60507/FK2/KB2RN6, bonndata, V1
The temporal order of a sequence of events has been thought to be reflected in the ordered firing of neurons at different phases of theta oscillations. Here we assess this by measuring single neuron activity (1,420 neurons) and local field potentials (921 channels) in the medial temporal lobe of 16 patients with epilepsy performing a working-memory... |

Gründemann, Jan; Hasegawa, Masashi; Huang, Ziyan; Paricio-Montesinos, Ricardo, 2025, "Network state changes in sensory thalamus represent learned outcomes", https://doi.org/10.60507/FK2/I2NSY2, bonndata, V1
Thalamic brain areas play an important role in adaptive behaviors. Nevertheless, the population dynamics of thalamic relays during learning across sensory modalities remain unknown. Using a cross-modal sensory reward-associative learning paradigm combined with deep brain two-photon calcium imaging of large populations of auditory thalamus (medial g... |

Tchumatchenko, Tatjana; Wert Carvajal, Carlos; Reneaux, Melissa; Clopath, Claudia, 2025, "Dopamine and serotonin interplay for valence-based spatial learning", https://doi.org/10.60507/FK2/JGONFT, bonndata, V1
Dopamine (DA) and serotonin (5-HT) are important neuromodulators of synaptic plasticity that have been linked to learning from positive or negative outcomes or valence-based learning. In the hippocampus, both affect long-term plasticity but play different roles in encoding uncertainty or predicted reward. DA has been related to positive valence, fr... |

Wieczorek, Tobias J.; Tchumatchenko, Tatjana; Wert-Carvajal, Carlos; Eggl, Maximilian, 2025, "A framework for the emergence and analysis of language in social learning agents", https://doi.org/10.60507/FK2/Z7NCOP, bonndata, V1
Neural systems have evolved not only to solve environmental challenges through internal representations but also, under social constraints, to communicate these to conspecifics. In this work, we aim to understand the structure of these internal representations and how they may be optimized to transmit pertinent information from one individual to an... |

Mohammadi, Ali; Fuhrmann, Falko; Tillmann, Jens F.; Fuhrmann, Martin; Schwarz, Martin K., 2025, "The Diagonal Band of Broca Regulates Olfactory-mediated Social Behaviors: A Study Using USVs As Unbiased, Ethological Markers For Social Interactions", https://doi.org/10.60507/FK2/WB6DOI, bonndata, V1
The Horizontal Diagonal Band of Broca (HDB) modulates olfactory information processing by recruiting olfactory bulb (OB) interneurons to shape excitatory OB output. Here, we show that OB is strongly and differentially innervated by HDB projections. Light-induced silencing of HDB afferents in the OB via OPN3 affected olfactory-mediated social habitu... |
Albert Miguel-Lopez; Negar Nikbahkt; Carlos Wert Carvajal; Lena Johanna Gschossmann; Martin Pofahl; Heinz Beck; Tatjana Tchumatchenko, 2025, "Transformations of the spatial activity manifold convey aversive information in CA3", https://doi.org/10.60507/FK2/9TSLYB, bonndata, V1
Hippocampal circuits form cognitive maps representing spatial position and integrating contextual information, including affective cues, within episodic memory representations. We investigated how spatial and affective information combine in the population activity of CA3 axons by imaging intermediate-to-dorsal and dorsal-to-dorsal projections in m... |
