The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

The Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Early evolution of the gular musculature and its innervation in ray‐finned fishes

The Anatomical Record, EarlyView.
Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Quantitative muscle architecture in large carnivorous marsupials (Marsupialia: Dasyuridae) and links to substrate use and prey processing

The Anatomical Record, EarlyView.
Abstract The Dasyurid species Sarcophilus harrisii, Dasyurus maculatus, and Dasyurus viverrinus, occupying diverse ecological niches and forming a guild structure in Tasmania, provide a basis for examining the roles of various forelimb muscle groups in prey capture and locomotion.

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Formation of Higher Habits

Nature, 1964
ALMOST since the beginning of the systematic study of performance experimenters had noticed the tendency for subjects to combine ‘elements’ into ‘groups’ for perceptual and motor purposes. One of the classic studies in human learning is the series of experiments on morse-learning by Bryan and Harter1, who showed some sixty-five years ago that the ...

Habit Formation and the Striatum

2016
Data from experimental animals and human subjects has provided convergent evidence for the key role of the striatum in the formation of stimulus-response habits. Habits can be distinguished from associative memories that support goal-directed actions based on their insensitivity to reward devaluation and contingency degradation.

Examining the Effect of Depressive Symptoms on Habit Formation and Habit-Breaking

Journal of Behavior Therapy and Experimental Psychiatry, 2020
Background and Objectives: Dysfunction in reward processing is a hallmark feature of depression. In the context of reinforcement learning, previous research has linked depression with reliance on simple habit-driven (‘model-free’) learning strategies over more complex, goal-directed (‘model-based’) strategies.

Moon formation and habitability in the circumplanetary habitable zone

2022
<p>We investigate the efficiency of moon formation around giant planets with numerical N-body simulations and study the habitability of Earth-sized, newly formed moons. Our results show that by the end of the moon formation process the individual mass of moons is higher, if the planet is in a close orbit around the host star. We also find
