The thalamus and cerebral cortex are intimately linked through strong topographical connections, not only from the thalamus to the cortex, but also from the cortex back to the thalamus. As in many parts of the brain, the basic circuit of thalamocortical connectivity is relatively simple, although intracortical and corticocortical connectivity provides ...

Spinothalamic and thalamocortical nociceptive pathways
The Journal of Pain, 2002The concept that the perception of a stimulus as being painful requires activity in parts of the cerebral cortex has gained universal recognition within the past 10 years. 28 The large number of functional imaging studies in humans, appearing during that period, have greatly contributed to this development by showing consistent evidence for activation ...

Connexon connexions in the thalamocortical system
2005Electrical synapses are composed of gap junction channels that interconnect neurons. They occur throughout the mammalian brain, although this has been appreciated only recently. Gap junction channels, which are made of proteins called connexins, allow ionic current and small organic molecules to pass directly between cells, usually with symmetrical ...

Abstract This chapter reviews how the cortex and thalamus interact to generate the characteristic electrical patterns of different sleep stages, changes in consciousness, and responsiveness to external stimuli during sleep. It reviews how features of NREM sleep (K complexes, sleep spindles, delta waves, and slow oscillations) are ...

During sleep, the mammalian brain generates an orderly progression of low frequency oscillations. The nature of these oscillations changes as the brain moves from sleep onset into deep sleep. Although readily measured and recorded, the underlying neural mechanisms involved and the purpose of these oscillations have remained unclear.

Nicotinic modulation of thalamocortical neurotransmission
2004Publisher Summary This chapter focuses on the thalamocortical neurons, which represent a major target for both acetylcholine (ACh) and nicotine. Although cholinergic nerve fibers and nicotinic receptors (nAChRs) are widely distributed in the brain, only a few sites of nicotinic cholinergic transmission are proposed.
