Microelectrode multiunit recording methods were used to determine the somatotopic organization of the second somatosensory area, S-II, in tree shrews. Neurons were activated by light tactile stimuli, and receptive fields were located on the contralateral body surface only. The orientation of S-II was such that the top of the head adjoined S-I and the distal limbs pointed away from S-I so that t...

Abstract In the present study, we reconstruct phylogenetic relationships within chromosomally variable Sorex araneus species group based on 20 nuclear loci and mitochondrial cyt b gene. tree, Nearctic S. arcticus represents earliest offshoot of followed by Holarctic tundrensis Siberian daphaenodon . Five other distributed mostly in Europe form a well‐supported clade. Coding regions showed stron...
