|
Cerebral Circulation: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | The major vessels of the anterior and posterior circulation are demonstrated along with the Circle of Willis on both a model and in an animation. The distribution of the three major cerebral arteries is demonstrated along with the concept of a watershed zone. A gross specimen with good vessels is al... | Cerebral Circulation; Brain; Dissections |

|
Cerebellum: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | The gross features of the cerebellum are shown. The three peduncles are demonstrated, noting their input and output to and from the cerebellum. Emphasis is given to symptoms of cerebellar disease appearing on the same side of the body. Special emphasis is given to cortical-cerebellar connections, st... | Cerebellum; Cortical-Cerebellar Connection; Brain; Dissection |

Sensation from the Body: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | Sensation consists of various modalities, which tend to travel in one of two pathways. The Anterolateral System also known as the Spinothalamic Tract carries pain and temperature. The Dorsal Column-Medical Lemniscus Pathway carries vibration, joint position, and fine 2-point discrimination. Light or... | Spinothalamic Tract; Anterolateral System; Dorsal Column-Medical Lemniscus Pathway; Body Sensation' Brain' Dissection |

Sensation from the Face: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | Sensation from the face travels in one of two pathways both of which eventually converge to form the trigeminothalamic tract that reaches the thalamus. The tract that carries pain and temperature is confusing because it first descends before crossing while the equivalent of Dorsal Column-Medical Lem... | Brain; Dissections |
