Abstract The star-nosed mole (Condylura cristata) has a snout surrounded by 22 fleshy and mobile appendages. This unusual structure is not an olfactory organ, as might be assumed from its location, nor is it used to manipulate objects as might be guessed from its appearance. Rather, the star is devoted to the sense of touch, and for this purpose the appendages are covered with thousands of small mechanoreceptive Eimer's organs. Recent behavioral studies find that the star acts much like a… 

Somatosensation in the superior colliculus of the star‐nosed mole

An SC dominated by somatosensory inputs in which neurons in all layers responded to mechanosensory stimulation is reported, forming a topographic representation of contralateral body dominated by the mechanosensor star of the star‐nosed mole.

Compartmentation of the Cerebellar Cortex: Adaptation to Lifestyle in the Star-Nosed Mole Condylura cristata

It is concluded that cerebellar architecture is generally conserved across the Mammalia but adapted to the specific lifestyle of the species.

Introduction: The World of Touch

This introductory overview is to give selected examples of research on important model organisms from various classes of the animal kingdom, ranging from the skin of worms to the feelers of insects, and from the whiskers of a rat to the human hand, and concludes by discussing forms of human touch and the possibility of its future extension via synthetic systems.

Is Cerebellar Architecture Shaped by Sensory Ecology in the New Zealand Kiwi (Apteryx mantelli)?

The expression of zebrin II (ZII) in the cerebellum of the kiwi, a fully nocturnal bird with auditory, tactile, and olfactory specializations and a reduced visual system, suggests a visual ecology unlike that of other birds.

Meissner corpuscles and somatosensory acuity: the prehensile appendages of primates and elephants.

Results show that greater MC density correlates with the extent to which primates are frugivorous; however, locomotor and/or phylogenetic effects cannot be discounted.

Electric imaging through active electrolocation: implication for the analysis of complex scenes

The electric sense of mormyrids is often regarded as an adaptation to conditions unfavourable for vision and in these fish it has become the dominant sense for active orientation and communication tasks, thus showing a degree of abstraction regarding the interpretation of sensory stimuli.

Insectivores are traditionally described as a primitive group that has not changed much in the course of mammalian evolution. In contrast, recent studies reveal a great diversity of sensorimotor

Ipsilateral representation of oral structures in human anterior parietal somatosensory cortex and integration of inputs across the midline

The findings indicate that, unlike nonhuman primates, humans have an ipsilateral representation of the lips in 3b/1, possibly related to the precise manipulation necessary for the articulation of speech.



Somatosensory fovea in the star‐nosed mole: Behavioral use of the star in relation to innervation patterns and cortical representation

It is reported that the 11th, ventral ray is the behavioral focus of the nose of the star‐nosed mole and has the largest cortical representation, greatest area of cortex per sensory organ, and the highest innervation density per sensory organs.

Organization of the somatosensory cortex of the star‐nosed mole

The results suggest that the primary somatosensory cortex, S1, has an unusual ventrolateral location and orientation with representations of mouth, nose rays, facial vibrissae, forepaw, and trunk in a rostrocaudal sequence.


This work began its studies by examining the sensory organs on the nose and by observing how the mole uses its nose to explore the environment, and it is covered with tens of thousands of complex touch sensors called Eimer's organs.

Structure and innervation of the sensory organs on the snout of the star‐nosed mole

The star‐nosed mole possesses a conspicuous specialization of its snout in the form of 22 fleshy appendages that fan out from around the nostrils, making this structure perhaps the most sensitive tactile organ yet discovered for its size.

The neural representation of visual space

It is reported here that estimates of Dr are obtained and their usefulness as predictors of M are examined and they are summarised in three basic equations.

Organization of somatosensory cortex and distribution of corticospinal neurons in the eastern mole (Scalopus aquaticus)

The somatotopic organization of somatosensory cortex of the eastern mole was explored with multiunit microelectrode recordings from middle layers of cortex, and dense corticospinal projections from the forelimb representation of S1 and motor cortex may reflect sensorimotor specializations related to digging behaviors in moles.

Preferential representation of the fovea in the primary visual cortex

It is reported here that ganglion cells near the fovea were allocated 3.3 to 5.9 times more cortical tissue than more peripheral ones, and it is concluded that the cortical representation of the most central retina is much greater than expected from the density of its ganglions.

Function of the star in the star-nosed mole, Condylura cristata

Star movements, mole behavior, and preliminary experiments are consistent with the hypothesis that the star-nosed mole uses an electrical sense to detect prey; conclusions must remain tentative until it is possible to obtain repeated responses from individual moles or from a larger sample of individuals.

Quantitative correlation between barrel-field size and the sensory innervation of the whiskerpad: a comparative study in six strains of mice bred for different patterns of mystacial vibrissae

In mice from 6 strains bred for different patterns of mystacial vibrissae, we studied the consequences of the presence of supernumerary whiskers for the sensory innervation of the vibrissal follicles

A comparison of the Eimer's organs of three north american moles: The hairy‐tailed mole (Parascalops breweri), the star‐nosed mole (Condylura cristata), and the eastern mole (Scalopus aquaticus)

The Eimer's organs of the star‐nosed mole are more numerous, smaller, and highly organized units with a consistent pattern of neuronal terminal swellings within a cell column, below a thin keratinized epidermis, and have no central cell column.
