A Cannibal Snake [PDF]

open access: yesNature, 1885
WITH reference to notes as to Ophiophagous snakes, which appeared at pp. 216, 269, 312, and 408 of the last volume of NATURE, I inclose a communication received by me this morning from Borneo. The habit seems general, and, according to the above letters, not confined to venomous or non-venomous varieties.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Subdivision based snakes for contour detection [PDF]

open access: yesarXiv, 2018
In this paper we propose a method for computing the contour of an object in an image using a snake represented as a subdivision curve. The evolution of the snake is driven by its control points which are computed minimizing an energy that pushes the snake towards the boundary of the interest region.

A taxonomic framework for typhlopid snakes from the Caribbean and other regions (Reptilia, Squamata)

open access: yes, 2014
The evolutionary history and taxonomy of worm-like snakes (scolecophidians) continues to be refined as new molecular data are gathered and analyzed. Here we present additional evidence on the phylogeny of these snakes, from morphological data and 489 new

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

open access: yesThe Anatomical Record, EarlyView.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

Pulvinar neurons reveal neurobiological evidence of past selection for rapid detection of snakes

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2013
Significance The present study shows preferential activity of neurons in the medial and dorsolateral pulvinar to images of snakes. Pulvinar neurons responded faster and stronger to snake stimuli than to monkey faces, monkey hands, and geometric shapes ...
