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 |

Hypothalamus: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | Gross specimens are used to demonstrate the area of the hypothalamus and its relationship to surrounding structures. Both endocrine and autonomic functions are explored using diagrams. Mention is made of the direct hypothalamic response to circulating hormones and other substances such as sodium. Th... | Hypothalamus; Brain; Dissection |

Three Critical Vertical Pathways: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | There is one motor and two sensory pathways that must be mastered. Pain and temperature from the body travel together and vibration and proprioception travel in another pathway each reaching perception in the cortex. Voluntary motor control starts in the cerebral cortex and connects with a motor neu... | Spinothalamic Tract; Dorsal Column-Medical Lemniscus Pathway; Posterior Column; Vertical Pathway; Brain; Dissection |

The Spinal Cord & Monosynaptic Reflex: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | The spinal cord's relationship to the foramina, discs and spinal nerves is demonstrated on a model. The dura, ganglia and rootlets are shown as well as the gray and white matter in gross sections at different levels. A model of the cord is used to demonstrate and describe the anatomy of a monosynapt... | Spinal Cord; Monosynaptic Reflex; Brain; Dissection |

Limbic System: Neuroanatomy Video Lab - Brain Dissections | Suzanne S. Stensaas, PhD | The decision was made to present a simplified description of a much more complex system using animations to construct a 3D image. Papez circuit is shown on gross specimens with mention of its involvement in memory. The role of the amygdala in fear and the olfactory cortex in temporal lobe epilepsy a... | Limbic System; Hippocampus; Brain; Dissection |
