Cognitive deficits in schizophrenia and other neuropsychiatric disorders: Convergence of preclinical and clinical evidence View all 29 Articles. Mammalian memory is the result of the interaction of millions of neurons in the brain and their coordinated activity. Candidate mechanisms for memory are synaptic plasticity changes, such as long-term potentiation LTP.

Lecture Notes. After getting acquainted, with the students introducing themselves and their background in neuroscience or lack thereof , we will discuss some basic concepts in neurophysiology that will help us understand the course material. In this meeting we will also learn about scientific manuscript writing, what to expect in a scientific paper and how each section is written.

We will also introduce the subject of the first two papers. Lecture 1 PDF 2 Scientific reading, writing and learning mechanisms of simple invertebrates The "Cake article" will be returned with comments and briefly discussed. We will discuss how defensive reflexes of invertebrates can teach us about mechanisms underlying learning and memory. Lecture 2 PDF 3 Synaptic plasticity in rodent hippocampal slices Learning and memory can be studied at many levels of complexity.

In this meeting we will see how pioneering research using brain slices discovered the basic physiological principals of plasticity in neuronal connections. We will discuss the impact of these findings on our understanding of memory and the molecular mechanisms underlying it.

Lecture 5 PDF 6 The Morris water maze The role of the hippocampus as an important brain structure necessary for performing learning related tasks was appreciated fully with the invention of the water maze. This elegant behavioral tool has been incorporated into the study of behavior at many levels, for understanding healthy brains and for the screening of rodent disease model systems. We will see examples of both. We will also discuss the abstracts written by the group. Lecture 6 PDF 7 Place cells After acquainting ourselves with the plasticity of neuronal circuits in the hippocampus and finding that this brain structure is necessary for rodents to find their place in the world, we can begin to investigate how it works.

The discovery of neurons in the hippocampus that fire in a place-specific manner allows us to connect the plastic molecular events we measure in brain slices with awake, behaving animals foraging for food in an arena.

We will see how place cells were discovered and how they are being studied today. We will see how many of the experimental techniques discussed in the course are carried out.

Field Trip PDF 9 NMDA receptors and place cells In this meeting we will discuss two papers that were published together in one issue of the journal Cell as two parts of a three part story. Here, Susumu Tonegawa introduced new molecular tools that facilitated the deletion of a molecule necessary for synaptic plasticity from one part of the hippocampal network. We will see how this affected synaptic plasticity, spatial learning and place cell formation.

Lecture 9 PDF 10 Hippocampal representation of space in contextual fear conditioning Learning to fear a potentially aversive context is a task that can be learned by rodents and measured by us.

This task may depend on the hippocampus and its role as a cognitive map. In this meaning we will explore how hippocampal representation relates to contextual fear conditioning. Lecture 10 PDF 11 Synaptic tagging In this meeting we will return to brain slices with studies that attempt to understand some of the mechanics of how long term memories are formed and stored. Lecture11 PDF 12 Other aspects of place cells We will learn about the 'grid cells' of the entorhinal cortex.

We will discus how this input information arriving at the hippocampus contributes to the formation of place cells. We will also see how analyzing place fields promotes our understanding of spatial memory in aging brains.

We will discuss examples of studies that were done to answer this question. Are they transferred to the cortex for long term storage? What are the temporal dynamics of such a process? Lecture 14 PDF. Need help getting started? Don't show me this again Welcome! In this meeting I will introduce myself and the format for the course.

Lecture 1 PDF. The "Cake article" will be returned with comments and briefly discussed. Lecture 2 PDF. Learning and memory can be studied at many levels of complexity. Lecture 3 PDF. We will discuss how NMDA receptors were implicated in the induction of LTP and how this idea still holds years later as molecular tools have been added to study the events underlying synaptic plasticity.

Lecture 4 PDF. Lecture 5 PDF. The role of the hippocampus as an important brain structure necessary for performing learning related tasks was appreciated fully with the invention of the water maze. Lecture 6 PDF. After acquainting ourselves with the plasticity of neuronal circuits in the hippocampus and finding that this brain structure is necessary for rodents to find their place in the world, we can begin to investigate how it works.

Lecture 7 PDF. Field Trip PDF. In this meeting we will discuss two papers that were published together in one issue of the journal Cell as two parts of a three part story. Lecture 9 PDF. Learning to fear a potentially aversive context is a task that can be learned by rodents and measured by us. Lecture 10 PDF. In this meeting we will return to brain slices with studies that attempt to understand some of the mechanics of how long term memories are formed and stored.

Lecture11 PDF. We will learn about the 'grid cells' of the entorhinal cortex. Do memories of context in space remain in the hippocampus?

It has been 70 years since Donald Hebb published his formalized theory of synaptic adaptation during learning.

Consolidation of implicit memory in the invertebrate Aplysia and explicit memory in the mammalian hippocampus are associated with remodeling and growth of preexisting synapses and the formation of new synapses. Here, we compare and contrast structural components of the synaptic plasticity that underlies these two distinct forms of memory. In both cases, the structural changes involve time-dependent processes. Thus, some modifications are transient and may contribute to early formative stages of long-term memory, whereas others are more stable, longer lasting, and likely to confer persistence to memory storage. In addition, we explore the possibility that trans-synaptic signaling mechanisms governing de novo synapse formation during development can be reused in the adult for the purposes of structural synaptic plasticity and memory storage. Finally, we discuss how these mechanisms set in motion structural rearrangements that prepare a synapse to strengthen the same memory and, perhaps, to allow it to take part in other memories as a basis for understanding how their anatomical representation results in the enhanced expression and storage of memories in the brain.

It has been 70 years since Donald Hebb published his formalized theory of synaptic adaptation during learning. Our understanding of the processes underlying learning and memory has been dominated by the view that synapses are the principal site of information storage in the brain. This view has received substantial support from research in several model systems, with the vast majority of studies on the topic corroborating a role for synapses in memory storage.

It is widely believed that spatial learning and memory require long-term changes in a brain region called the hippocampus. This review challenges this received wisdom and uses recent evidence to argue that, rather than encoding or storing spatial memories, the hippocampus may use spatial information to resolve conflict and reduce uncertainty. This may explain its role in anxiety as well as memory.


nervous system. In its most general form, the “synaptic plasticity and memory hypothesis” states that during formation of memories appropriate synapses.

Еще толком не отдавая себе отчета в своих действиях и повинуясь инстинкту, она резким движением согнула ноги и со всей силы ударила Хейла коленом в промежность, ощутив, как ее коленные чашечки впились в его мягкие незащищенные ткани. Хейл взвыл от боли, и все его тело сразу же обмякло.
