The art of forgetting by Ivan Izquierdo( )

8 editions published in 2015 in English and held by 238 WorldCat member libraries worldwide

How do we forget? Why do we need to forget? This book intends to answer to these and other questions. It aims to demonstrate that each one is who it is due to their own memories. Thus, distinguish between the information we should keep from those we should forget is an difficult art. In this book, the author discusses about the different types of memory, the main types of forgetting (avoidance, extinction and repression), their brain areas and their mechanisms. In this sense, the art of forgetting, or the art of do not saturate our memory mechanisms, is something innate, that benefits us anonymously, keeping us from sinking amidst our own memories. The essays that compose this book go through several aspects, since individuals to societies' memory. By the end of the book, the reader will be able to understand that we forget to be able to think, to live and to survive

El arte de olvidar by Ivan Izquierdo( Book )

1 edition published in 2008 in Spanish and held by 3 WorldCat member libraries worldwide

"¿Por qué olvidamos tal o cual hecho, y recordamos aquel otro, que se niega por años a desaparecer de nuestra memoria? ¿Cómo funcionan nuestros recuerdos, esa corriente misteriosa y oculta que de repente, por un detalle casual, sale a la superficie y nos devuelve un momento de nuestras vidas? ¿Cuál es el sistema que gobierna estos movimientos de la mente? Si es que hay un sistema, por supuesto ... Con una prosa sencilla y con la sabiduría y experiencia de haber investigado este tema durante más de cuatro décadas, nos explica cómo se forman las memorias, pues no se trata de una sino de varias, cuáles permanecen y cuáles no, y por qué; nos ilumina sobre las funciones que cumple cada una de ellas en la vida diaria: retener un número de teléfono, un evento trascendental, un aroma o una idea. El arte de olvidar nos descubre las razones veladas de nuestros olvidos, y lo indispensable que resulta olvidar. Si recordáramos continuamente todo seríamos presa del pasado, es decir, seríamos menos creativos, y también menos libres. Y al mismo tiempo, si prescindiéramos por completo de él, no podríamos disfrutar las enseñanzas del tiempo. Por eso olvidar (y recordar) es un arte, que se cultiva y aprende, un arte que debemos reconocer si queremos aprovechar lo mejor de nosotros mismos."--Contratapa
Short- and long-term memory: differential involvement of neurotransmitter systems and signal transduction cascades by Monica R. M Vianna( )

1 edition published in 2000 in English and held by 2 WorldCat member libraries worldwide

Since William James (1890) first distinguished primary from secondary memory, equivalent to short- and long-term memory, respectively, it has been assumed that short-term memory processes are in charge of cognition while long-term memory is being consolidated. From those days a major question has been whether short-term memory is merely a initial phase of long-term memory, or a separate phenomena. Recent experiments have shown that many treatments with specific molecular actions given into the hippocampus and related brain areas after one-trial avoidance learning can effectively cancel short-term memory without affecting long-term memory formation. This shows that short-term memory and long-term memory involve separate mechanisms and are independently processed. Other treatments, however, influence both memory types similarly, suggesting links between both at the receptor and at the post-receptor level, which should not be surprising as they both deal with nearly the same sensorimotor representations. This review examines recent advances in short- and long-term memory mechanisms based on the effect of intra-hippocampal infusion of drugs acting upon neurotransmitter and signal transduction systems on both memory types.

Memory of inhibitory avoidance in the rat is regulated by glutamate metabotropic receptors and by calcium/calmodulin kinase II in the hippocampus by Marino Bianchin( )

1 edition published in 1995 in English and held by 1 WorldCat member library worldwide

We studied the effect on memory of the bilateral intrahippocampal posttraining infusion of the glutamate metabotropic receptor (mGLUR) agonist, 1S,2R-aminocyclopentane dicarboxylate (ACPD), of the mGLUR antagonist, [RS]-alpha-methyl-4-carboxyphenyl glycine (MCPG), and of the inhibitor of calcium/calmodulin protein kinase II (CaM II), 1-[N, O-Bis (5-isoquinolinesulfonyl)-N-methyl-L-tyrosyl]-4-phenyl piperazine (KN62). Male Wistar rats were implanted with cannulae in the CA1 region of the dorsal hippocampus. After recovery from surgery they were trained in a step-down inhibitory avoidance task and tested for retention 24 h later. Immediately or 180 min after training they received an intrahippocampal infusion of saline (0.5 mul), KN62 (100 mumoles), ACPD (20 nmoles), MCPG (13 nmoles) or of ACPD plus MCPG in 0.5 mul of saline. When given immediately after training, KN62 and MCPG were amnestic and ACPD caused memory facilitation and antagonized the effect od MCPG. When given 180 min after training, the drugs had no effect on memory. The results indicate that the early phase of memory is regulated by mGLURs in the hippocampus and requires CaM II activity. The data support the suggestion that memory involves long-term potentiation in the hippocampus. (AU)
Synaptic messenger substances in memory processes by Ivan Izquierdo( )

1 edition published in 1995 in English and held by 1 WorldCat member library worldwide

Nitric oxide (NO), carbon monoxide (CO), the platelet-activating factor (PAF) and arachidonic acid are released by stimulated neurons, enhance glutamate release at nerve terminals and have been proposed as synaptic messengers involved in plastic phenomena, such as the long-term potentiation of glutamatergic synapses. Long-term potentiation has been suggested to be a basic mechanism of memory processes. The microinjection of inhibitors of the synthesis of NO and CO or of antagonists of the receptors to PAF into brain structures known to be involved in memory (hippocampus, amygdala, entorhinal cortex), during its early phases, causes amnesia. This indicates that NO, CO and PAF modulate the early phases of memory, perhaps by modulating long-term potentiation. In addition, microinjections of a NO releaser or of a soluble form of PAF into the hippocampus produce memory enhancement. (AU)
Evidence that similar neurotransmitter mechanisms in amygdala, hippocampus and medial septum regulate memory consolidation of avoidance behavior in rats by Claudio da Cunha( )

1 edition published in 1991 in English and held by 1 WorldCat member library worldwide

A injecao de acido DL-amino-5-fosfonopentanoico (AP5) ou escopolamina na amigdala, no septo medial ou no hipocampo, imediatamente apos o treino, causa amnesia retrograda para um aprendizado de esquiva inibitoria em ratos. A picrotoxina, no entanto, causa facilitacao retrograda da memoria e bloqueia o efeito do AP5 e da escopolamina. O timolol nao tem efeito proprio mas cancela as acoes da picrotoxina. O AP5 e um antagonista de receptores a N-metil-D- aspartato (NMDA) dos aminoacidos excitatorios; a escopolamina e um antagonista dos receptores colinergicos muscarinicos; a picrotoxina bloqueia o canal de cloro estimulado pelos receptores GABA-A; e o timolol e um antagonista dos ̄adrenoreceptores. Os resultados indicam que, na amigdala, no septo medial e no hipocampo, receptores NMDA e muscarinicos sao necessarios para a consolidacao da memoria, receptores GABA-A inibem a acao dos anteriores, e receptores ̄noradrenergicos modulam a acao dos receptores GABA-A.A amigdala, o septo medial e o hipocampo operam de forma nao redundante na consolidacao da memoria (AU)
