- Guarding the gateway to cortex with attention in visual thalamus : Abstract : Nature: Attention modulates visual signals before they even reach cortex by increasing responses of both magnocellular and parvocellular neurons in the LGN. At the same time, attention decreases neuronal responses in the adjacent thalamic reticular nucleus (TRN).

- Molecular Correlates of Laminar Differences in the Macaque Dorsal Lateral Geniculate Nucleus -- Murray et al. 28 (46): 12010 -- Journal of Neuroscience: Cellular localization of gene expression revealed 11 new layer-specific markers, of which 10 were enriched in magnocellular layers (BRD4, CAV1, EEF1A2, FAM108A1, IN{alpha}, KCNA1, NEFH, NEFL, PPP2R2C, and SFRP2) and one was enriched in parvocellular and koniocellular layers (TCF7L2).

- Consciousness and Anesthesia -- Alkire et al. 322 (5903): 876 -- Science: This is a must-read review which is dealing with difference between unconscious and conscious states of global brain activity. Basically, this review is a brief summary of several chapters in a recent text book (The Neurology of Consciousness) , which is more intense. I basically agree on their view but also I feel that this is still hard to fill the gap between evidence and theory. And also I think that Tononi's theory just replaces explanation of Baars' theory. We need a theory at intermediate-l evel between abstract level and more empirical level in order to test hypotheses by experiments.

- Rapid Changes in Thalamic Firing Synchrony during Repetitive Whisker Stimulation -- Temereanca et al. 28 (44): 11153 -- Journal of Neuroscience: Employing whisker deflections varying in velocity or frequency and a CCG analysis, the authors find systematic changes in both time course and strength f thalamic firing synchrony as a function of stimulus parameters and sensory adaptation.

- Effect of subchronic galantamine treatment on neur...[Neurop harmacology. 2004] - PubMed Result: AChE overexpressing mice (hAChE-Tg) and control mice (FVB/N) were treated with galantamine (4mg/kg/day) for 10 days. FVB/N mice noted a significant increase in alpha4 nicotinic receptor binding in the CA1 and CA3 area of the hippocampus and a significant increase of alpha7 nicotinic receptor binding in the frontal cortex, retrosplenial gr. cortex, motor cortex, and thalamus. Reductions in muscarinic receptors (m2-muscarinic + m1-muscarinic) were observed in several brain regions of both mice types.

Those synapses are strong but show short-term depression.

- Capitalizing on Deep Brain Stimulation: Thalamus as a Language Monitor: Neuron -- Münte and Kutas: Intralaminar/m idline thalamus is involved in language comprehension, let's say detecting errors. This previews sucks but I think that Wahl et al might be interesting for other contexts.

- The Human Thalamus is Crucially Involved in Executive Control Operations: MIT Press Journals - Journal of Cognitive Neuroscience - Abstract: NoGo related activity in the human thalamus (the ventral intermediate nucleus, VIM).
