 The Limbic System contains many areas including the _____ and _____ | Cortical and Deeper Subcortical regions |
| Cortical Regions include: (4x) | Orbital and Medial Prefrontal Cingulate Gyrus Insula Parahippocampal |
| Deeper Cortical Structures include: | Hippocampus Amygdala Ventral Striatum Nucleus Accumbens |
| Limbic System (Cortical and Subcortical) along with other CNS structures provide basis of: (3x) | Memory Motivation Emotions |
| Examples of Limbic system basics: Planning | Frontal and Cingulate Cortex |
| Cognition | Cerebral Cortex |
| Stress | HPA Axis Hippocampus Amygdala |
| Fear | Amygdala |
| Memory | Hippocampus and Entorhinal Cortex |
| Neuromodulatory Pathways to Limbic Structures (4x) | Norepinephrine (NO) Dopamine Serotonin (5HT) Acetyl Choline (Ach) |
| Norepinephrine: From | Locus Ceruleus in Pons |
| Norepinephrine | -Attentional Selectivity under Stress -Activates large areas of brain |
| Dopamine: From | Ventral Tegmentum in Midbrain |
| Dopamine | -Facilitates working memory in PFC |
| The _____Dopamine System promotes Reward Seeking behavior | Mesolimbic |
| Serotonin (5HT) location | Raphe Nucleus in Medulla |
| Serotonin (5HT) | Mood Sleep/Wake Cycles |
| Acetyl Choline: Location | Septum Nucleus Basalis and Diagnal band of Broca |
| Acetyl Choline | Facilitate Hippocampal and other Cortical regions in memory and cognition |
| Hippocampus: The ______ in the Medial Temporal Lobe, bulges into Lateral Ventrical | Archicortex *in the 16th century , the Hippocampus was named after the seahorse because of its curled appearance in cross section |
| Hippocampal Afferents: Cortex: | Sensory, Association, Cingulate, and Prefrontal Cortex project into Temporal Lobe *Parahippocampal Gyrus: ---> Entorohinal Cortex ---> Hippocampus and Amygdala |
| Hippocampal Afferents: Septum (Ach) | Diagnol band of Broca and other monoamine pathways |
| Hippocampal Efferents: Fornix carries contextually processed information to : | -Hypothalamus (Neuroendocrine responses) *regulates stress and visceral symptoms -Prefrontal, Cingulate, and Temporal Cortex (consolidate memory in cortex) |
| Limbic system is well known for developing certain types of _____ | Memory |
| _____ and ____ (of the Hippocampus) are associated with Declaritive Memory | Hippocampus and Medial Temporal Lobe |
| _____ (of the Hippocampus) is associated with the emotional type of Procedural Memory | Amygdala |
| _____(of the Hippocampus) is associated with Working Memory | Prefrontal Cortex *Short term Memory |
| Declaritive Memory is also known as | Explicit Memory |
| Declarivitive (Explicit) Memory consists of the following two types | Episodic Semantic |
| Episodic Memory : Location | Hippocampus and Hippocampal Cortices -memory for specific autobiographical episodes or events ( you were there/ you experienced it ) -Content of Experience and Spacial and Temporal context (what's all around you/what will sustain the memory ) - Auto-noetic consciousnes (i.e. with self in it) -Memory of experience of event |
| Semantic Memory: Location | Limbic Cortes: Anterolateral: (Temporal, Ventrtolateral Prefrontal Cortex) -Non-Contexual content of experience or knowledge of the world -Long term representation of facts, concepts, word meanings, ect (i.e. abstract features) -Noetic Conciousness (consciousness of knowledge without a sense of self and experience accompanying it |
| With time, Episodic memory becomes altered to | Semantic Memory |
| Episodic and Semantic memory is located in the | Posterior part of the Temporal Lobe |
| Procedural (or Implicit) Memory, will be covered later, but note how skills and habits use (3x) | Basal Ganglia Cerebellum Posterior Cortex |
