String-pulling for food by the rat: Assessment of movement, topography and kinematics of a bilaterally skilled forelimb act

Autor: Ashley A. Blackwell, Jenny R. Köppen, Ian Q. Whishaw, Douglas G. Wallace

Publikováno v: Learning and Motivation. 61:63-73

A variety of behavioral tests have been developed to assess skilled forelimb function in the rat, including tests that assess use of a single limb in reaching for food and placing it in the mouth for eating. The present study describes bilateral hand

Cholinergic deafferentation of the hippocampus causes non-temporally graded retrograde amnesia in an odor discrimination task

Autor: Joseph L. Cheatwood, Philip A. Blankenship, Jenny R. Köppen, Douglas G. Wallace, Ashley A. Blackwell, Megan L. Sieg, Sarah L. Stuebing

Publikováno v: Behavioural Brain Research. 299:97-104

Dementia of the Alzheimer's type (DAT) is a neurodegenerative disorder marked by loss of hippocampal cholinergic tone and significant memory impairments, specifically for memories acquired prior to disease onset. The nature of this relationship, howe

Comparison of direction and distance estimation across spatial tasks: Absence of sexually dimorphic self-movement cues processing

Autor: Sarah S. Stuebing, Shawn S. Winter, Ashley A. Blackwell, Leslie Matuszewich, Jenny R. Köppen, Douglas G. Wallace, Philip A. Blankenship

Publikováno v: Learning and Motivation. 51:11-24

Animals use many sources of information to maintain spatial orientation, including cues from the environment and cues generated by self-movement. In general, sexual dimorphisms have been observed in humans and rodents in tasks that afford access to e

Analysis of movement kinematics on analogous spatial learning tasks demonstrates conservation of direction and distance estimation across humans (Homo sapiens) and rats (Rattus norvegicus)

Autor: Danielle Grimelli, Douglas G. Wallace, Shawn S. Winter, Eileah L. Loda, Jenny R. Köppen, Derek A. Hamilton, Brianne P. Apger

Publikováno v: Journal of Comparative Psychology. 127:179-193

This series of experiments evaluates the nature of the representation that mediates human (Homo sapiens) and rat (Rattus norvegicus) movement characteristics on analogous spatial learning tasks. The results of Experiment 1 demonstrated that self-move

Limbic system structures differentially contribute to exploratory trip organization of the rat

Autor: Shawn S. Winter, Douglas G. Wallace, Tialia B.N. Ebert, Jenny R. Köppen

Publikováno v: Hippocampus. 23:139-152

The role of limbic system structures in spatial orientation continues to be debated. The hippocampus (HPC) has been implicated in encoding symbolic representations of environments (i.e., cognitive map), whereas entorhinal cortex (EC) function has bee

Infusion of GAT1-saporin into the medial septum/vertical limb of the diagonal band disrupts self-movement cue processing and spares mnemonic function

Autor: Joseph L. Cheatwood, Jenny R. Köppen, Sarah L. Stuebing, Shawn S. Winter, Douglas G. Wallace

Publikováno v: Brain structurefunction. 218(5)

Degeneration of the septohippocampal system is associated with the progression of Dementia of the Alzheimer’s type (DAT). Impairments in mnemonic function and spatial orientation become more severe as DAT progresses. Although evidence supports a ro

Navigating with fingers and feet: analysis of human (Homo sapiens) and rat (Rattus norvegicus) movement organization during nonvisual spatial tasks

Autor: Jeana L. Jones, Steve J. Wagner, Douglas G. Wallace, Jenny R. Köppen, Shawn S. Winter

Publikováno v: Journal of comparative psychology (Washington, D.C. : 1983). 124(4)

The current set of studies examines the contribution of movement segmentation to self-movement cue processing for estimating direction and distance to a start location in humans and rats. Experiments 1 and 2 examined the extent that ambulatory dead r
